Margie is purchasing a $45.00 pair of boots. She has 3 coupons to the

store that she can choose from:

Coupon 1: $10 off purchase

Coupon 2: 15% off purchase

Coupon 3:

5 off purchase

Use coupon 1.

Step-by-step explanation:

$10 off 45.00 = $35.00

15% =

10% = 4.5

5% = 2.25

So: 4.5 + 2.25 = 6.75 (15% = $6.75)

So 45.00 - 6.75 = $38.25

And coupon 3 is just 5 off. So you would want to use the first coupon on $10 off ...
