Question

Kyra has a manufacturer's coupon for $5 off a box of diapers and a store coupon for 20% off any purchase. The store will let you use both coupons, but it does not have a policy about which coupon you must use first. What order should she use the coupons to get the maximum discount on a $40 box of diapers?

Answer 1

There are two possible orders Kyra can use the coupons:

1. Use the 20% off store coupon first, and then the $5 off manufacturer's coupon:

- 20% off $40 = $8 discount
- $40 - $8 = $32
- $32 - $5 = $27 final price

2. Use the $5 off manufacturer's coupon first, and then the 20% off store coupon:

- $40 - $5 = $35
- 20% off $35 = $7 discount
- $35 - $7 = $28 final price

Therefore, using the first order (20% off store coupon first) gives Kyra the maximum discount of $27.
