— Petitioners Patrick S. Inniss, Sam R. Lopez and Adnan I. Haq seek review of a decision of the Court of Appeals, Division One, which affirmed an order of summary judgment by the King County Superior Court in favor of their employer, Respondent Tandy Corporation, in their action challenging calculation of their overtime compensation. The Court of Appeals concluded in an unpublished opinion the employment practice of a “fluctuating workweek” did not violate the Washington Minimum Wage Act, chapter 49.46 RCW, when calculating overtime compensation at “one and one-half times the regular rate” under RCW 49.46.130(1)1 We granted review. We affirm.
QUESTION PRESENTED
The question presented in this case is whether the employment practice of utilizing a “fluctuating workweek” violates the Washington Minimum Wage Act when calculating overtime compensation at “one and one-half times the regular rate” under RCW 49.46.130(1).
STATEMENT OF FACTS
The material facts are not in dispute.2 Respondent Tandy Corporation is a Delaware corporation doing business in Washington as Radio Shack.3 Petitioners Patrick S. Inniss, Sam R. Lopez and Adnan I. Haq were “V” store managers at various Radio Shack stores in King County from 1993 to *5201996.4 Each worked at least 40 hours a week, the exact number of hours fluctuating from week to week.5 Overtime hours were paid in accordance with the “Radio Shack Retail Store Manager Compensation Plan for ‘V’ Stores,” portions of which provide:
B. Employment Relationship. This compensation plan is not an employment contract but only a method of calculating the manager’s total earnings and it is understood that the employment relationship with Radio Shack is an at will relationship.
C. Base Pay. The “V” Store Manager will be paid a base salary as straight time pay for all hours worked each workweek. The base salary shall be determined by the number of complete years of continuous service worked as a Radio Shack Retail Store Manager and shall be structured as shown in the chart below. The base salary will be paid on a weekly or bi-weekly basis as determined by state law.
Overtime will be paid at one-half the calculated regular rate (obtained by dividing the number of hours worked in the workweek into the weekly base salary amount) for all hours worked over forty (40) in any workweek.
Tenure Salary Weekly Examples of annual pay for 54 hour workweek
Less than 1 year $15,938 $306.50 $18,000
1 to 2 years $16,819 $323.45 $19,000
2 to 3 years $17,706 $340.50 $20,000
3 to 4 years $18,590 $357.50 $21,000
More than 4 years $ 19,479 $374.60 $22,000
Adjustments to the base pay for tenure shall be effective at the beginning of the first pay period beginning after the completion *521of each full year of continuous service as a retail store manager.
L. Work Week, [sic] The manager will typically be scheduled to work 6 days per week.[6]
In 1993, the minimum hourly wage in the State of Washington for an employee “who [had] reached the age of eighteen years” was $3.85 per hour.7 Effective from January 1, 1994 to December 31, 1998, the minimum hourly wage was increased to $4.90 per hour.8 Petitioners “concede that if all of [Petitioners’] commissions, [special incentive bonuses] and bonuses (including annual bonuses) are included in determining [Petitioners’] regular rate of pay, [Petitioners] received at least [the statutory minimum hourly wage].”9
On October 9, 1996, Petitioners filed a complaint against Respondent in the King County Superior Court claiming they were not compensated “at a rate of one and one-half times their regular rate of pay for [their] overtime work”10 as required by the Washington Minimum Wage Act.11 On April 17, 1997, they filed a motion for partial summary judgment on the validity of Respondent’s compensation plan for overtime hours under a “fluctuating workweek.”12 Respondent filed a cross-motion for summary judgment on May 2, 1997.13 The Honorable Michael J. Trickey on June 30, 1997 signed an order granting Respondent’s motion for *522summary judgment and denying Petitioners’ motion.14 The trial court concluded, as a matter of law, that Respondent’s method of calculating overtime compensation under a “fluctuating workweek” did not violate the Washington Minimum Wage Act.15
On July 23, 1997, Petitioners filed a notice of appeal to the Court of Appeals, Division One.16 The Court of Appeals, the Honorable Ronald E. Cox writing, affirmed the order granting summary judgment.17 It concluded in an unpublished opinion that Respondent’s compensation of its managers under the fluctuating workweek method did not violate the Washington Minimum Wage Act because Petitioners’ wages never fell below the statutory minimum.18
Petitioners Inniss, Lopez and Haq petitioned this Court for review of the decision of the Court of Appeals. Review was granted on January 7, 2000.19
DISCUSSION
Standard of Review
This Court reviews an order of summary judgment de novo.20 It engages in the same inquiry as the trial court, treating all facts and reasonable inferences from the facts in a light most favorable to the nonmoving party.21 Where, as here, the parties do not dispute the material facts, this Court will affirm an order on summary judgment if the *523successful moving party is entitled to judgment as a matter of law.22
Interpretation of a statute is a question of law.23 At issue in this case is the interpretation of RCW 49.46.130(1), which reads:
Minimum rate of compensation for employment in excess of forty horn* work week [sic] — Exceptions. (1) Except as otherwise provided in this section, no employer shall employ any of his employees for a work week [sic] longer than forty hours unless such employee receives compensation for his employment in excess of the hours above specified at a rate not less than one and one-halftimes the regular rate at which he is employed.
(Emphasis added.)
The Washington Minimum Wage Act24 does not define the term “regular rate” under RCW 49.46.130(1)25 But under its compensation plan for “V” store managers, Respondent Tandy Corporation defined “regular rate” as the “weekly base salary amount” divided by the “number of hours worked in the workweek.” Petitioners Inniss, Lopez and Haq contend that because their total work hours fluctuate from week to week, Respondent’s definition violates the Washington Minimum Wage Act when calculating overtime compensation under RCW 49.46.130(1)26
In 1975, the Legislature enacted RCW 49.46.130 to conform state minimum wage laws to the federal Fair Labor Standards Act of 1938.27 The wording of RCW 49.46.130(1) is similar to the wording of 29 U.S.C. § 207 (a)(1), which reads:
*524(a) Employees engaged in interstate commerce; additional applicability to employees pursuant to subsequent amendatory provisions.
(1) Except as otherwise provided in this section, no employer shall employ any of his employees who in any workweek is engaged in commerce or in the production of goods for commerce, or is employed in an enterprise engaged in commerce or in the production of goods for commerce, for a workweek longer than forty hours unless such employee receives compensation for his employment in excess of the hours above specified at a rate not less than one and one-halftimes the regular rate at which he is employed.
(Emphasis added.) The Fair Labor Standards Act of 193828 also does not define the term “regular rate.”29
When construing provisions of the Washington Minimum Wage Act, this Court may consider interpretations of comparable provisions of the Fair Labor Standards Act of 1938 as persuasive authority.30
In Walling v. A.H. Belo Corp., the United States Supreme Court recognized the complexity of employment relationships and declined to provide a rigid definition of “regular rate” under the Fair Labor Standards Act of 1938.31 It concluded, however, in Overnight Motor Transportation Co. v. Missel, that the term “regular rate” was flexible enough to permit calculation of overtime compensation for a fluctuating workweek.32
In Missel, an employee worked irregular hours for a fixed *525weekly wage and “brought a statutory action to recover alleged unpaid overtime compensation” under the Fair Labor Standards Act of 1938.33 The United States Supreme Court stated:
No problem is presented in assimilating the computation of overtime for employees under contract for a fixed weekly wage for regular contract hours which are the actual hours worked, to similar computations for employees on hourly rates. Where the employment contract is for a weekly wage with variable or fluctuating hours the same method of computation produces the regular rate for each week. As that rate is on an hourly basis, it is regular in the statutory sense, inasmuch as the rate per hour does not vary for the entire week, though week by week the regular rate varies with the number of horns worked.[34]
This Court may also consider the Code of Federal Regulations (C.F.R.) as persuasive authority.35 The United States Department of Labor has promulgated an administrative regulation which defines the term “regular rate” in the context of a fluctuating workweek, published in 29 C.F.R. § 778.114, which reads:
§ 778.114 Fixed salary for fluctuating hours.
(a) An employee employed on a salary basis may have hours of work which fluctuate from week to week and the salary may be paid him pursuant to an understanding with his employer that he will receive such fixed amount as straight time pay for whatever hours he is called upon to work in a workweek, whether few or many. Where there is a clear mutual understanding of the parties that the fixed salary is compensation (apart from overtime premiums) for the hours worked each workweek, whatever their number, rather than for working 40 hours or some other fixed weekly work period, such a salary arrangement is permitted by the Act if the amount of the salary is sufficient to provide compensation to the employee at a rate *526not less than the applicable minimum wage rate for every hour worked in those workweeks in which the number of hours he works is greatest, and if he receives extra compensation, in addition to such salary, for all overtime hours worked at a rate not less than one-half his regular rate of pay. Since the salary in such a situation is intended to compensate the employee at straight time rates for whatever hours are worked in the workweek, the regular rate of the employee will vary from week to week and is determined by dividing the number of hours worked in the workweek into the amount of the salary to obtain the applicable hourly rate for the week. Payment for overtime hours at one-half such rate in addition to the salary satisfies the overtime pay requirement because such hours have already been compensated at the straight time regular rate, under the salary arrangement.
(b) The application of the principles above stated may be illustrated by the case of an employee whose hours of work do not customarily follow a regular schedule but vary from week to week, whose overtime work is never in excess of 50 hours in a workweek, and whose salary of $250 a week is paid with the understanding that it constitutes his compensation, except for overtime premiums, for whatever hours are worked in the workweek. If during the course of 4 weeks this employee works 40, 44, 50, and 48 hours, his regular hourly rate of pay in each of these weeks is approximately $6.25, $5.68, $5, and $5.21, respectively. Since the employee has already received straight-time compensation on a salary basis for all hours worked, only additional half-time pay is due. For the first week the employee is entitled to be paid $250; for the second week $261.36 ($250 plus 4 hours at $2.84, or 40 hours at $5.68 plus 4 hours at $8.52); for the third week $275 ($250 plus 10 hours at $2.50, or 40 hours at $5 plus 10 hours at $7.50); for the fourth week approximately $270.88 ($250 plus 8 hours at $2.61 or 40 hours at $5.21 plus 8 hours at $7.82).
(c) The “fluctuating workweek” method of overtime payment may not be used unless the salary is sufficiently large to assure that no workweek will be worked in which the employee’s average hourly earnings from the salary fall below the minimum hourly wage rate applicable under the Act, and unless the employee clearly understands that the salary covers whatever hours the job may demand in a particular workweek and the *527employer pays the salary even though the workweek is one in which a full schedule of hours is not worked. Typically, such salaries are paid to employees who do not customarily work a regular schedule of hours and are in amounts agreed on by the parties as adequate straight-time compensation for long workweeks as well as short ones, under the circumstances of the employment as a whole. Where all the legal prerequisites for use of the “fluctuating workweek” method of overtime payment are present, the Act, in requiring that “not less than” the prescribed premium of 50 percent for overtime hours worked be paid, does not prohibit paying more. On the other hand, where all the facts indicate that an employee is being paid for his overtime hours at a rate no greater than that which he receives for nonovertime hours, compliance with the Act cannot be rested on any application of the fluctuating workweek overtime formula.
(Emphasis added.)
As illustrated under 29 C.F.R. § 778.114(b), the employment practice of a “fluctuating workweek” requires an employee to work hours which vary from week to week. There are two components necessary for determining the total weekly compensation for an employee under a fixed salary with fluctuating hours.
The first component is compensation for “straight time” or a normal 40-hour workweek. Straight time pay is calculated at the “regular rate” based upon a ratio of weekly base salary to total hours worked in the workweek, including overtime hours.36
The second component is compensation for overtime work. Overtime pay is based upon hours in excess of 40 hours per *528week and calculated at “one and one-half times the regular rate.”37
Combining the two components results in an employee’s total weekly compensation, which may thus be expressed in a mathematical formula as:
40 hours x r "N Weekly Base Salary 40 hours+ overtime hours V J +Overtime Hours x 1.5 x Weekly Base Salary 40 hours + overtime hours Total weekly compensation
The formula assumes an employee has a workweek of at least 40 hours for “straight time pay.” But even if thé employee works less than 40 hours, an employer and employee may operate under a clear mutual understanding that the weekly base salary is straight time “compensation (apart from overtime premiums) for the hours worked each workweek, whatever their number. . . .”38 Because overtime hours will “have already been compensated at the straight time regular rate,” overtime compensation would then be calculated at one-half the regular rate of pay.39
An employee’s total weekly compensation may then be expressed as:
Weekly Base Salary r + Overtime Hours V. X 0.5 x r y'' Weekly Base Salary 40 hours + overtime hours _ J _ Total Weekly Compensation
Under this formula, 0.5 x (weekly base salary 4 (40 hours *529+ overtime hours)) is equivalent to the “hourly rate per week.” As the number of overtime hours increases, there is a corresponding decrease in the hourly rate per week because the weekly base salary remains constant. If the weekly base salary is $250.00 and an employee works one hour of overtime, the hourly rate per week is $3.05 per hour.40 But if the weekly base salary is $250.00 and an employee works 128 hours of overtime in a workweek (for a total of 168 hours), the hourly rate per week is startlingly reduced to $0.74.41
The regressive reduction of hourly rate with a corresponding increase in overtime hours is illustrated on this chart:
[[Image here]]
The Washington State Department of Labor and Industries, following the approach utilized under 29 C.F.R. § 778.114, permits “the regular rate of pay. . . [to] be determined by dividing the amount of compensation received per week by the total number of hours worked during that week.”42 Petitioners nevertheless cite the Alaska case *530of Dresser Industries, Inc. v. Alaska Department of Labor43 to support their claim that this approach produces unfair results in violation of the Washington Minimum Wage Act.44
“It is true that the longer the hours, the less the rate and the pay per hour. This is not an argument, however, against [the fluctuating workweek] method of determining the regular rate of employment for the week in question.”45 Petitioners’ reliance on Dresser Industries is misplaced because the sole issue in that case was whether the Alaska Department of Labor had authority under the Alaska Wage and Hour Act to promulgate a regulation which prohibited the “flexible work week [sic]” method of calculating overtime compensation 46 Unlike the issue in Dresser Industries, which related only to authority to promulgate regulations, the question in this case is whether Respondent’s calculation of Petitioners’ overtime compensation under a *531fluctuating workweek violates ROW 49.46.130(1) under the Washington Minimum Wage Act.
In this case, Respondent’s compensation plan (which declares it is “not an employment contract”) defines “regular rate” by “dividing the number of hours worked in the workweek into the weekly base salary amount.” It provides a chart in which a weekly base salary of $306.50 results in annual pay of $18,000.00 for a 54-hour workweek. Respondent is following the approach adopted by the United States Department of Labor and the Washington State Department of Labor and Industries. The total weekly compensation for a 54-hour workweek is calculated under the following formula:
14 hours C$306-50 ~j _ Total Weekly + overtime x 1-5 x I 54 hours J Compensation 40 hours $306.50 54 hours
In simpler form, application of the formula results in the following determination of total weekly compensation:
Straight time pay
40 hours x $5.68 $227,20
Overtime pay
14 hours x 1.5 x $5.68 119.28
Total weekly compensation $346.48
With 52 weeks in a year, annual pay under this formula would total $18,016.96.
As stated in Missel, expressing the regular rate on an hourly basis per week still produces regularity “in the statutory sense, inasmuch as the rate per hour does not vary for the entire week. . . .”47 Respondent chose not to calculate the regular rate as “hourly rate” but as a ratio of weekly base salary to total hours worked in a workweek. The Washington Minimum Wage Act permits this choice. The Legislature defined overtime compensation for employees of retail and service establishments and certain com*532missioned salespeople in terms of an “hourly rate.”48 Yet it chose to define overtime compensation under RCW 49.46.-130(1) in the more generalized term of a “regular rate.” In making this distinction and not defining “regular rate” in the Minimum Wage Act, the Legislature apparently intended to allow a broad and flexible interpretation of the term so long as the purposes of the Washington Minimum Wage Act are satisfied. One such purpose is to establish a minimum for employee compensation.49
Petitioners served as managers for Respondent from 1993 to 1996. In 1993, the minimum wage was $3.85 per hour, and effective from January 1, 1994 to December 31, 1998 it was increased to $4.90 per hour. The Court of Appeals correctly stated that because Petitioners’ wages never fell below the statutory minimum, Respondent complied with the requirements of the Washington Minimum Wage Act. The statutory minimum has two components based upon the minimum hourly wage under RCW 49.46.-020: one for straight time pay and one for overtime pay. Straight time pay is calculated by multiplying the 40 hours in a normal workweek by the minimum hourly wage under RCW 49.46.020. Overtime pay is calculated by multiplying the number of overtime hours at a rate of one and *533one-half times the minimum hourly wage. Combining the components of straight time pay and overtime pay results in the statutory minimum.50
If the total weekly compensation for any of the Petitioners were less than the statutory minimum for that week, Respondent would have violated the Washington Minimum Wage Act. This is not the case, however. Petitioners “concede that if all of [Petitioners’] commissions, [special incentive bonuses] and bonuses (including annual bonuses) are included in determining [Petitioners’] regular rate of pay, [Petitioners] received at least [the statutory minimum hourly wage].”51
Respondent’s calculation of overtime compensation under a fluctuating workweek does not violate RCW 49.46.130(1) under the Washington Minimum Wage Act. The Court of Appeals correctly observed that persuasive authorities interpreting a comparable provision under the Fair Labor Standards Act of 1938 support Respondent’s Statutory Minimum Minimum Hourly Wage Under RCW 49.46.020 Overtime Hours Minimum Hourly Wage Under RCW 49.46.020 definition of “regular rate” as a ratio of weekly base salary to the total number of hours worked in a workweek. Similarly, interpretation of the term “regular rate” under RCW 49.46.130(1) is sufficiently broad and flexible to permit Respondent to calculate overtime compensation under a fluctuating workweek. In doing that, Respondent does not violate a stated purpose of the Washington Minimum Wage Act because the actual weekly compensation for each Petitioner was never less than the *534total weekly compensation based upon the minimum hourly wage under RCW 49.46.020.
SUMMARY AND CONCLUSION
This Court reviews an order of summary judgment de novo and will affirm an order if the moving party is entitled to judgment as a matter of law. Interpretation of a statute is a question of law. At issue in this case is interpretation of RCW 49.46.130(1) of the Washington Minimum Wage Act, which requires employers to compensate their employees for overtime hours “at a rate not less than one and one-half times the regular rate . . . .” The term “regular rate” is not defined in the statute.
In the absence of a definition, this Court may consider United States Department of Labor interpretations of “regular rate” under 29 U.S.C. § 207 (a)(1) of the Fair Labor Standards Act of 1938 as persuasive authority. Those authorities permit “regular rate” to be interpreted broadly and flexibly as a ratio of weekly base salary to the total number of hours worked in a workweek even if the hours fluctuate from week to week. By distinguishing between “hourly rate” and “regular rate” and by modeling RCW 49.46.130(1) after 29 U.S.C. § 207 (a)(1), the Legislature allowed a broad and flexible interpretation of the term “regular rate” under RCW 49.46.130(1) so long as the purposes of the Washington Minimum Wage Act are satisfied. One of those purposes is to establish a minimum for employee compensation.
In this case, the material facts are not in dispute. Each Petitioner worked at least 40 hours a week, the exact number of hours fluctuating from week to week. Under its compensation plan, Respondent defined “regular rate” as a ratio of the weekly base salary to the total number of hours worked in a workweek. Although the ratio decreases as the total number of hours increases, Respondent’s definition is a permissible interpretation of the term “regular rate” under RCW 49.46.130(1) because the term is subject to a broad and flexible interpretation unless Respondent vio*535lated a stated purpose of the Washington Minimum Wage Act, a fact not established in this case. Petitioners conceded that their total compensation exceeded that required under the statutory minimum hourly wage. Regardless what our reaction may be to the compensation provided its management employees by Respondent Tandy Corporation, we note that in this case it is based upon voluntary acceptance by Petitioner employees of the compensation plan promulgated in writing by Respondent employer. Although the plan boldly states it is “not an employment contract,” it has the characteristics of a contract. We need not decide whether it is an express contract, a quasi contract, a unilateral contract or a bilateral contract. With the purported disclaimer, it may be an illusory contract, but we need not decide that issue either. Neither party challenges the validity of the compensation plan which was acknowledged by Petitioners and Respondent to be a valid operating document.
As a matter of law, Respondent’s calculation of Petitioners’ overtime compensation under a fluctuating workweek as specified in Respondent’s compensation plan did not violate RCW 49.46.130(1) under the Washington Minimum Wage Act.
We affirm the decision of the Court of Appeals, Division One, which affirmed the order of summary judgment by the King County Superior Court in favor of Respondent Tandy Corporation.

*530“Salary — Fluctuating Hours: When an employee is employed on a fixed salary and it is understood that the hours will fluctuate from week to week, and it is clearly understood that the fixed salary constitutes straight time pay for all hours of work, whatever the number. The regular rate is obtained for each week by dividing the salary by the number of hours worked in the week. Since it was understood that all hours would constitute straight time, all hours worked have already been paid at straight time compensation; however, the employee is still entitled to receive additional overtime compensation for each hour over 40 in the week at not less than one-half the regular rate.
“Example: An employee is hired at a fixed salary of $1,500.00 per month, with the understanding that this salary represents compensation regardless of the number of hours worked each week. The salary is converted to its weekly equivalent ($1,500.00 x 12 = 52). The weekly salary ($346.15) is then divided by the number of hours worked that week. During the course of three weeks the employee works 45, 48 and 50 hours. The regular hourly rate of pay in each of these weeks, respectively, is: $7.69, 7.21 and 6.92; straight time pay for all hours worked has already been paid at these regular rates, and only an additional half-time pay is due for each hour over 40. In addition to receiving the weekly salary of $346.15 for each week, the first week an additional payment of $19.25 (5.0 x $3.85) is due, second week $28.88 (8 x $3.61), and the third week $34.60 (10 hrs x $3.46).”
