Answer 1

5. Nathan will not spend enough to use the coupon. His purchase will cost $89.27

6. Ana bought 1 pair of sunglasses, 1 t-shirt, and 1 towel.

7. Austin should get $34.50 back

Explanation:

Nathan

Cost of Board shorts x Number of pairs bought = Cost of Board shorts

Cost of towel x Number of towels bough = Cost of towels

Total (Board shorts) + Total (Towels) = Final price total

25.99 X 3 = 77.97

5.65 X 2 = 11.30

77.97+11.30 = 89.27

Ana

$33.90-$15.50-$12.75=$5.65

Austin

2 shirts = 12.75+12.75 (12.75 X 2) = 25.50

60.00 - 25.50 = 34.50
