Support computing sales tax in the CashRegister class. The tax rate should be supplied when constructing a CashRegister object. Add recordTaxablePurchase and getTotalTax methods. (Amounts added with recordPurchase are not taxable.) The giveChange method should correctly reflect the sales tax that is charged on taxable items. Please add the method to the CashRegisterTester. The input and output are also provided below.
