Question

Mary is buying several items that cost $128.25 total. She is using a store coupon for 35% off her purchases. She has to pay 4% sales tax. Calculate the total cost of the items.

Answer 1

The coupon is 35% off, therefore, she actually paid 65%

0.65(128.25) = 83.36 (what she paid without tax)

now we add the sales tax of 4%

83.36 (1.04) = 86.69 <== total cost
