Question

Before going back to college, Brandy goes shopping at Bed Bath & Beyond to get items for her dorm. She didn't keep track of all the items in her cart but knows that she spent more than $90. She has two coupons that she wants to use and is trying to decide in what order she should use them. Which order makes the most sense? Explain your reasoning.

Answer 1

20% then $15 off

Explanation:

20% coupon first saves 90(0.20)=$18, making the new total $72. Subtracting $15 gives $57.

$15 coupon first makes the new balance $75, and 20% off that makes the new total 75(0.80)=$60.

So, to save more money, she should use the 20% coupon first, then the $15 coupon.
