Question

Andrea is shopping for items for her pet sitting business because the store is having a sale where everything in the store is 5% off. Andrea buys a cat carrier for $39.99 and a cat tower for $19.99. She has a coupon for an additional 15% off on the cat tower. Before tax, Andrea estimates that her total, after discounts, will be about $54. Determine if Andrea has estimated correctly.

A. Yes, Andrea has estimated correctly

Explanation:

I just took the test on edg.

Answer 2

Given:
cat carrier : 39.99
cat tower: 19.99
1st discount : 5%
2nd discount: 15% - cat tower

39.99 * 5% = 1.99
39.99 - 1.99 = 38

19.99 * (5% + 15%) = 19.99 * 20% = 3.99
19.99 - 3.99 = 16

38 + 16 = 54

Andrea estimated correctly.
