Martin finds a shirt on sale for 10% off at a department store. The original
price was $20. Martin must also pay 8.5% sales tax. (Example 3)
a. How much is the shirt before taxes are applied?
b. How much is the shirt after taxes are applied?

Answer 1

The answer is a 13 NB 19

Answer 2

A:18 B:19.53

Explanation:

For part A you will have to do 20 * 0.10 ( you get 0.10 by 10/100 or 10 ÷ 100) which is 2, you then have to do 20 - 2 since 2 is the discount amount which is 18.

For part B: You do 8.5 /100 to get 0.085 for tax, you then do 18 * 0.085 = 1.53 which is the tax amount. You add 18.00 + 1.53 and get 19.53.

Hope this helps!

Edit: * = Multiplication
