Question

PLS HELP ME ASAP!!! 10 POINTS!!

a) Isaac is purchasing two pairs of shoes—one pair for $37.00 and the second pair for $42.00. The state sales tax applied to Isaac’s bill is 7%. How much is Isaac’s total bill? Show your work.
b) If Isaac uses a coupon entitling him to a 25% discount off the purchase price before tax, how much will his bill be? Assume that a 7% sales tax is applied to the discounted price. Using words, explain how you found the discounted price.
c) The shoe store clerks are paid on commission. If the clerk receives a 12% commission on total purchase amounts before tax is applied, how much would the commission be for Isaac’s purchase with and without a coupon?

Answer 1

a) $84.53

37+42=79

79(0.07)=5.53

79+5.53=84.53

b) $56.50

You have to multiply the cost of both shoes by 0.25 to get the amount of money that Isaac gets discounted. Then you subtract that amount from the cost of the shoes to get the new price. Then you multiply the new price by 0.07 to get how much he will be taxed. Finally, you add the tax to the total.

c) Before the coupon is applied: $10.08

After the coupon is applied: $9.48

84(0.12)=10.08

79(0.12)=9.48

Explanation:
