Question

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. How much is the shirt before taxes are applied? How much is the shirt after tax is applied?

Answer 1

multiply 20x.01 which equals 2. subtract that from 20 wich gives you 18
$18
multiply 18x.085 which equals 1.53. add that to 18 and that is your answer
$19.53 after

Answer 2

The shirt is $18 before taxes are applied.
10% of 20 is 2. 20-2=18.
After taxes are applied the shirt is $19.53.
8.5% of 18 is 1.53. 1.53 + 18 = $19.53
