Question

Shaun purchased a shirt for $22.05. If this includes. If this includes 5% sales tax, what was the actual price of the shirt?

Answer 1

$21.00

x + .05x = 22.05
1.05x = 22.05
x = 22.05/1.05
x = $21.00

Answer 2

If it includes the 5% tax, this means that $22.05 is 105% of the original price.

Let's set up a proportion.

22.05/105 = x/100

100*1.05=105
x*1.05=22.05

Divide both sides by 1.05
x=21

Final answer: $21
