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 issac's purchase with a coupon?

After tax: $78

Before tax: $59,25

Step-by-step explanation:

First, find the total cost:

$79 + $5,53 = $84,53

Next, find the cost before tax:

−$19,75 + 79 = $59,25

Then find the cost after tax:

**$18,75 = $4,1475

$59,25 + $18,75 = $78

To sum up, we deduced the discount percentage from the total cost. We have also taken the percentage of the tax from the discounted amount and added the discounted amount for overall cost in order to calculate the discounted price with tax.
