Question

A shirt cost $21 last month. This month the price decreased by 30%. What is the new price?

Answer 1

$14.7

Explanation:

First, we need to convert the percentage to a decimal. 30% = .30

Now we multiply the price times the decimal, 21 x .30 = 6.3

We subtract this amount from the previous cost. 21 - 6.3= $14.7

Answer 2

$14.70

Explanation:

Find the 30% decrease:

21*0.3 = 6.3

Find new price:

21-6.3 = 14.7
