OPINION
MANDERINO, Justice.The appellants, Nate Goodman and Voss & Goodman, Inc., filed a complaint in equity seeking to enjoin the en*318forcement of the criminal statute proscribing the Sunday sales of fresh meats, produce and groceries. Act of June 24, 1939, P.L. 872, § 699.15, as amended, 18 P.S. § 4699.-15 (recodified as 18 Pa. S. § 7364). Following a hearing, relief was denied and this appeal followed.
The appellant, Nate Goodman, is the sole owner of all of the stock of the corporate appellant, Voss & Goodman, Inc., which operates a grocery store in Erie, Pennsylvania, under the name of Paul Bunyan. The Paul Bunyan store, which has always employed ten or more persons, carries a standard line of grocery store items. In addition, the store has a delicatessen department which sells prepared foods such as salads, sandwiches, baked beans, chicken and spareribs. In 1972, the Paul Bunyan store and twenty-eight other stores in Erie County were subjected to arrests for Sunday sales.
The present action was filed on December 6, 1972, in an attempt to gain relief from multiple arrests. Since the filing of the action, the Act challenged has been repealed and reenacted. 18 Pa. S. § 7364. The appellants’ cause of action, however, is not rendered moot by the reenactment. Since the wording of the new act is identical to the old Act, with one change which we shall later discuss, the appellants’ challenge is properly before us. The Statutory Construction Act of 1972, 1 Pa. S. § 1962, states “[w] henever a statute is repealed and its provisions are at the same time reenacted in the same or substantially the same terms by the repealing statute, the earlier statute shall be construed as continued in active operation. All rights and liabilities incurred under such earlier statute are preserved and may be enforced.”
The new grocery act, with certain exceptions, prohibits any person from engaging in the business of selling or otherwise dealing at retail in fresh meats, produce and groceries on Sunday. 18 Pa. S. § 7364. There are three *319exceptions in the law. The law states that the prohibition does not apply to any retail establishment:
(1) employing less than ten persons;
(2) where fresh meats, produce and groceries are offered so [sic] sold by the proprietor or members of his immediate family; or
(3) where food is prepared on the premises for human consumption.
(The word or appeared between the word offered and the word sold in the repealed statute. The word so in the reenacted statute is an obvious misprint.)
In Bertera’s Hopewell Foodland, Inc. v. Masters, 428 Pa. 20, 236 A.2d 197 (1967), this Court held that the grocery act and the exceptions to the act did not violate either the federal or the state constitutions. Appellants raise no issue concerning the constitutionality of the general prohibition in the act. The issues raised concern the exceptions and the alleged discriminatory enforcement of the act.
I.
The appellants urge that we consider our decision in Bertera that the first exception is constitutionally valid. They contend that that exception denies them the equal protection of the laws in violation of their Fourteenth Amendment rights, and constitutes a special law in violation of the Pennsylvania Constitution. See Pa. Const, art. 3, § 7, § 32(7), P.S. Both of these arguments were considered and rejected in Bertera. We must again reject these arguments.
Bertera held that the words “employing less than ten persons” did not mean “employing less than ten persons” on Sunday, but meant “employing less than ten persons” at any time. The Statutory Construction Act of 1972 gives us the following guide in Section 1922:
“In ascertaining the intention of the General Assembly in the enactment of a statute the following presump*320tions, among others, may be used: . . . [t]hat when a court of last resort has construed the language used in a statute, the General Assembly in subsequent statutes on the same subject matter intends the same construction to be placed on such language.”
1 Pa. S. § 1922.
Since the legislature, after the Bertera decision, reenacted the first exception using words identical to those in the act at the time of the Bertera decision, we should presume that the legislature intended the first exception to mean what we said it meant in Bertera.
The legislative decision to except retail establishments “employing less than ten persons” at any time was within the legislature’s constitutional discretion. McGowan v. Maryland, 366 U.S. 420, 81 S.Ct. 1101, 6 L.Ed.2d 393 (1961) pointed out that enforcement considerations are relevant in determining the reasonableness of legislative classifications. The test chosen by the legislature avoids some problems of enforcement of a Sunday closing law. The test chosen would permit enforcement officers to periodically obtain information as to the number of employees employed by a given retail establishment, and to maintain a list of those establishments permitted to open under the exception. To determine if the statute was being obeyed, stores open on Sunday could simply be checked against this list. If all retail grocery establishments were permitted to remain open on Sunday so long as no more than nine employees were working on any given Sunday, no one could see an open store and know whether the law was being violated. Enforcing the statute would require a weekly check of the interior of every store open on Sunday to determine how many employees were working. The legislature could have concluded that such enforcement considerations dictated that the exception apply only to those stores employing “less than ten” at any time.
*321The appellants contend that this division of retail establishments selling the same commodities into two different classifications based solely on the number of employees is arbitrary, and results in economic harm to the appellants. Initially, we note that all statutory classifications permitting one class to be treated differently than another class, involve some measure and type of harm to one of the classes. Such discrimination, however, does not make the classification unconstitutional. The legislature has the constitutional authority to establish different classifications of persons and to provide for different treatment of the classifications under the law so long as the basis for each classification is reasonably related to the evils sought to be prevented. In McGowan v. Maryland, 366 U.S. 420, 425, 81 S.Ct. 1101, 1105, 6 L.Ed.2d 393, 399 (1961), the Court stated the equal protection test as follows:
“Although no precise formula has been developed, the Court has held that the Fourteenth Amendment permits the States a wide scope of discretion in enacting laws which affects some groups of citizens differently than others. The constitutional safeguard is offended only if the classification rests on grounds wholly irrelevant to the achievement of the State’s objective. State legislatures are presumed to have enacted within their constitutional power despite the fact that, in practice, their laws result in some inequality. A statutory discrimination will not be set aside if any state of facts reasonably may be conceived to justify it.” (citations omitted).
The test for determining the validity of legislative classifications under provisions of article 3, of the Pennsylvania Constitution, prohibiting special laws, is not significantly different. Bargain City U.S.A. v. Dilworth, 407 Pa. 129, 179 A.2d 439 (1962); see also Chartiers Valley Joint Schools v. County Board of School Directors v. Boehm, 418 Pa. 520, 211 A.2d 487 (1965).
*322The state has a valid interest in providing a day of rest and recreation for members of the public, and general proscriptions against Sunday sales are constitutional. Many exceptions to the general prohibitions have been upheld because of a recognition that the public’s enjoyment of the day of rest and recreation can be enhanced by the employment of some on the day set aside for the rest and recreation of others. Two Guys from Harrison-Allentown, Inc. v. McGinley, 366 U.S. 582, 81 S.Ct. 1135, 6 L.Ed.2d 551 (1961); McGowan v. Maryland, 366 U.S. 420, 81 S.Ct. 1101, 6 L.Ed.2d 393 (1961); Bertera’s Hopewell Foodland, Inc. v. Masters, 428 Pa. 20, 236 A.2d 197 (1967).
The appellants, however, argue that the legislative selection of the number nine has no reasonable basis, any more than the number eight or the number ten or any other number. The use of mathematical limitations as the basis for separate classifications in the law is constitutional so long as the number selected bears a reasonable relationship to a legitimate legislative objective. Carmichael v. Southern Coal and Coke Company, 301 U. S. 495, 57 S.Ct. 868, 81 L.Ed. 1245 (1937), held valid a state statute that imposed upon some employers — but not all — the obligation to pay a certain percentage of their monthly payrolls into the state unemployment compensation fund. The statutory classification excluded from its operation employers of less than eight employees. Carmichael said:
“Distinctions in degree, stated in terms of differences in number, have often been the target of attack . . . . It is argued here, and it was ruled by the court below, that there can be no reason for a distinction, for purposes of taxation, between those who have only seven employees and those who have eight. Yet, this is the type of distinction which the law is often called upon to make. It is only a difference in numbers which marks the moment when day ends and *323night begins, when the disabilities of infancy terminate and the status of legal competency is assumed. It separates large incomes which are taxed from the smaller ones which are exempt, as it marks here the difference between the proprietors of larger businesses who are taxed and the proprietors of smaller businesses who are not.
“Administrative convenience and expense in the collection or measurement of the tax are alone a sufficient justification for the difference between the treatment of small incomes or small taxpayers and that meted out to others.”

Illinois, 185 U.S. 203, 207, 22 S.Ct. 616, 46 L.Ed. 872, 875 (coal mines employing five or more subject to inspection); McLean v. Arkansas, 211 U.S. 539, 551, 29 S.Ct. 206, 53 L.Ed. 315, 321 (mines employing ten or more required to measure coal for payment of wages before screening); Booth v. Indiana, 237 U.S. 391, 397, 35 S.Ct. 617, 59 L.Ed. 1011, 1017 (mines required to supply washhouses upon demand of twenty employees); Jeffrey Mfg. Co. v. Blagg, 235 U.S. 571, 576, 35 S.Ct. 167, 59 L.Ed. 364, 368, 7 N.C.C.A. 570; Middleton v. Texas Power & L. Co., 249 U.S. 152, 159, 39 S.Ct. 227, 63 L.Ed. 527, 532 (employers of five or more included within workmen’s compensation act).
In Shankey v. Staisey, 436 Pa. 65, 257 A.2d 897 (1969), we held that election laws denying positions on the general election ballot to persons failing to obtain a certain minimum of public support were constitutional. The classification was drawn in terms of the number of petition signatures or primary votes that such a candidate had secured. We held the numerical classification valid, because there was a legitimate legislative objective in avoiding an unduly complicated ballot even though the *324classification discriminated against some persons. Likewise, in Chartiers Valley Joint School v. County Board of School Directors v. Boehm, 418 Pa. 520, 211 A.2d 487 (1965), we upheld a numerical classification, in the school code, which treated school districts having more than 4,000 pupils differently than school districts having less than 4,000 pupils.
Many other existing laws classify according to a legislatively selected number. A legislatively selected number of dollars divides those who may sue in a particular court from those who may not, a legislatively selected number of years divides those who may successfully be sued on a contract from those who may not; a legislatively selected number of days divides those who may have redress in the courts from those who may not.
In the grocery act, the legislatively selected number of “less than ten” reasonably relates to legitimate legislative objectives. The legislature may establish provisions permitting some people to be employed so that others may enjoy their day of rest and recreation. It chose to achieve this objective by providing that retail establishments employing less than ten persons may remain open. We have no basis upon which to conclude that its choice was unreasonable. Had the legislature chosen a number such as ten thousand, there might be a basis for concluding that the number had no reasonable relationship to the legislative objective. Such a number might completely thwart the legitimate legislative objective of providing a day of rest and recreation. On the other hand, we could hardly invalidate an exception which would allow a retail establishment employing only one employee to remain open. The Maryland Sunday closing law, considered in McGowan v. Maryland, 366 U.S. 420, 81 S.Ct. 1101, 6 L.Ed.2d 393 (1961), contained such an exception, and it was not declared unconstitutional. McGowan pointed out that each of the many exceptions had to be upheld if any state of facts could justify the exception. *325Obviously, somewhere between the number one and the number ten thousand, the line of constitutional validity might be crossed, but we cannot say the line was crossed when the legislature selected “less than ten.”
The legislature is to be given wide discretion in classifying, and any judicial inquiry into legislative classifications should not concern itself with the wisdom of the legislative choices so long as the choices are reasonably related to legitimate legislative objectives. Levy v. Louisiana, 391 U.S. 68, 88 S.Ct. 1509, 20 L.Ed.2d 436 (1968); Loving v. Virginia, 388 U.S. 1, 87 S.Ct. 1817, 18 L.Ed.2d 1010 (1967); McGowan v. Maryland, 366 U.S. 420, 81 S.Ct. 1101, 6 L.Ed.2d 393 (1961); Safeway Stores v. Oklahoma Retail Groc. Assoc., 360 U.S. 334, 79 S.Ct. 1196, 3 L.Ed.2d 1280 (1959); Chartiers Valley Joint School v. County Board of School Directors v. Boehm, 418 Pa. 520, 211 A.2d 487 (1965); Bargain City U.S.A. v. Dilworth, 407 Pa. 129, 179 A.2d 439 (1962).
A legislative classification need not be made with “mathematical nicety.” Inequalities may result as long as some reasonable basis is apparent for the classification. Dandridge v. Williams, 397 U.S. 471, 90 S.Ct. 1153, 35 L.Ed.2d 491 (1970); Equitable Credit & Discount Co. v. Geier, 342 Pa. 445, 31 A.2d 53 (1941).
We are, therefore, unable to conclude that the legislature’s choice of “less than ten” employees as the dividing line between the classifications for purposes of prohibiting Sunday sales violates either article 3 of the Pennsylvania Constitution or the fourteenth amendment. We thus reaffirm our Bertera decision as to the first exception.
II.
The next issue concerns the second exception. It per. mits retail establishments to remain open “where fresh meats, produce and groceries are offered [or] sold by the *326proprietor or members of his immediate family.” 18 Pa. S. § 7364(c)(2). At the time Bertera’s Hopewell Foodland, Inc. v. Masters, 428 Pa. 20, 37, 236 A.2d 197, 206 (1967), was decided, this exception contained additional language which Bertera interpreted to mean that any retail establishment could remain open “where fresh meats, produce and groceries are offered or sold by the proprietor or members of his immediate family and employing less than ten persons.” (Emphasis added.) See Act of June 24, 1939, P.L. 872, § 699.15, as amended, 18 P.S. § 4699.15. In the reenactment of the second exception, the legislature deleted the italicized language. The reasoning of Bertera as to this exception is therefore not controlling. This was the only change made when the grocery act was repealed and reenacted.
The second exception now classifies retail establishments into those where the commodities are offered or sold by persons who are members of the same family and those where like commodities are offered or sold by persons who are not members of the same family. The former are allowed to open on Sunday but the latter are not. The separate classifications are based solely on the family status of those offering or selling the commodities. The exception thus gives an economic advantage to certain groups solely because of the degree of consanguinity. Groups similarly situated, except for the degree of consanguinity, thereby suffer economic harm.
Bertera did not specifically consider whether a classification based solely on family status was reasonably related to the legitimate legislative objective to be attained by the Sunday closing laws. Bertera assumed that economic discrimination in favor of stores classified solely on the basis of family status, in and of itself, was a legitimate legislative objective. We cannot agree. Economic discrimination, in and of itself, is not a legitimate legislative objective which justifies the closing of some stores on Sunday and not others. Economic dis*327crimination can be tolerated constitutionally only when it is incidental to some other legitimate legislative objective. A classification based on family status might be reasonably related to a legitimate legislative objective in other contexts, even though economic discrimination incidentally results, but we are unable to perceive any reasonable relationship in the present context. Without such relationship, the family status classification violates the equal protection clause of the fourteenth amendment, Morey v. Doud, 354 U.S. 457, 77 S.Ct. 1344, 1 L.Ed.2d 1485 (1957); Smith v. Cahoon, 283 U.S. 553, 51 S.Ct. 582, 75 L.Ed. 1264 (1931); Commonwealth v. Daniel, 430 Pa. 642, 243 A.2d 400 (1968), and violates article 3 of the Pennsylvania Constitution which prohibits special laws. Kurtz v. City of Pittsburgh, 346 Pa. 362, 31 A.2d 257 (1943); Commonwealth v. Casey, 231 Pa. 170, 80 A. 78 (1911). To the extent that Bertera is inconsistent with this opinion, it is overruled.
III.
The appellants next contend that the trial court erred in holding that the appellants’ entire retail establishment could not remain open on Sunday under the third exception. That exception allows the Sunday opening of a retail establishment “where food is prepared on the premises for human consumption.” 18 Pa. S. § 7364(c)(3). The trial court found that the Paul Bunyan store, which occupied eight thousand square feet, used five hundred square feet for the preparation of food for human consumption within the meaning of the third exception in the grocery act. The trial court held, therefore, that the appellants could open that portion of the premises devoted to the preparation of food for human consumption. The trial court, however, denied the appellants the right to open the remaining portion of the store which was not used for the preparation of food for human consumption. The appellants argue that the entire retail establishment *328may remain open even though only five hundred square feet is used for a purpose qualifying for the third exception. We cannot agree.
The interpretation urged by the appellants would mean that a retail establishment employing any number of employees would be permitted to open on Sunday if any portion of the premises qualified for the third exception. Under the Statutory Construction Act, in ascertaining legislative intent, we are to consider the object to be attained by a statute. 1 Pa. S. § 1921(c) (4). We are also to consider the consequences of a particular interpretation. 1 Pa. S. § 1921(c)(6). We must presume that the General Assembly does not intend a result that is absurd or unreasonable. 1 Pa. S. § 1922(1). The consequences of the interpretation suggested by the appellants would render ineffective the general prohibition against the Sunday sales of fresh meats, produce and groceries. The legislative objective of providing for a day of rest and recreation would be thwarted. We are thus unable to accept appellants’ interpretation. The trial court properly held that the appellants’ entire retail establishment could not remain open under the third exception.
IV.
The appellants’ final claim is that the trial court erred in concluding that the grocery act had not been discriminatorily applied against them. Although the record establishes that there was a lack of uniformity in the enforcement of the Sunday closing law, there is no evidence in the record to establish that the lack of uniformity was the result of purposeful discrimination aimed at a particular class of which the appellants were members. A purposeful discrimination must be shown and we cannot presume such discrimination. Snowden v. Hughes, 321 U.S. 1, 64 S.Ct. 397, 88 L.Ed. 497 (1943); *329Yick Wo v. Hopkins, 118 U.S. 356, 6 S.Ct. 1064, 30 L.Ed. 221 (1885).
y.
The only remaining question is whether the unconstitutional second exception in the grocery act is severable from the remaining portions of the act. The Statutory Construction Act of 1972, 1 Pa. S. § 1925, provides:
“The provisions of every statute shall be severable . unless the court finds that the valid provisions of the statutes are so essentially and inseparably connected with, and so depend upon, the void provision or application, that it cannot be presumed the General Assembly would have enacted the remaining valid provisions without the void one; or unless the court finds that the remaining valid provisions, standing alone, are incomplete and are incapable of being executed in accordance with the legislative intent.”
Under the guidelines provided, we conclude that the unconstitutional second exception is severable. The constitutional provisions of the grocery act are not “essentially and inseparably connected with, and . dependent upon,” the unconstitutional second exception. We cannot presume that the General Assembly would not have enacted the constitutional portions of the act without the unconstitutional second exception. The constitutional portions of the act are complete and capable of execution in accordance with the legislative intent.x
Since the appellants’ entire store may not open on Sunday under either the first or third exceptions, they remain subject to the general prohibition against the Sunday sale of fresh meats, produce and groceries, and are not entitled to injunctive relief.
