Complete Question

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%.

1) How much is isaac’s total bill? show your work

2) 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.

3) The shoe store’s 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?

Total price of the shoes bought by Isaac = $37 + $42 = $79

1) With a sales tax of 7%, how much does Isaac pay?

The total payable amount will now be (1 + 7%) of the price of the shoes bought by Isaac.

That is, 1.07 × 79 = $84.53

2) There's a 25% discount and a 7% sales tax after the discount.

The price of the shoes after the discount would be (1 - 25%) of $79

That is, (1 - 0.25) × 79 = 0.75 × 79 = $59.25

Then, a sales tax of 7% brings the payable amount to (1 + 7%) of $59.25

That is, (1.07 × 59.25) = $63.3975 = $63.40

3) Store clerk's commission = 12% of shoe price before sales tax

Without the coupon, the price of the shoes = $79.

Store clerk's commission = 12% of $79 = 0.12 × 79 = $9.48

With the 25% discount coupon, price of the shoes becomes 0.75 × 79 = $59.25

Store clerk's commission = 12% of $59.25 = 0.12 × 59.25 = $7.11
