Question

Lin's father is paying for a $20 meal. He has a 15%-off coupon for the

meal. After the discount, a 7% sales tax is applied. What does Lin's
father pay for the meal? Explain or show your reasoning.

Answer 1

18.19

Explanation:

15% of 20 = 3

20 - 3 = 17

7% of 17 = 1.19

17 + 1.19 = 18.19
