Question

1. A sweater was originally $15.00, but the department store is running a 15% off sale. What is

the sale price of the sweater?

Answer 1

$12.75

Explanation:

$15 * (1 - 0.15)

(where -0.15 is the amount deducted from the sale)

$15 * (1-0.15) =

$12.75

Answer 2

$12.75

Explanation:

Firstly, you'd multiply $15.00 by 15%, then you'd get 2.25.

Secondly, you would $15.00-$2.25=$12.75.

Therefore, $12.75 is 15% off.
