The original price of a jacket was $45. It was on sale for $38. What was the percent of the discount?

15.5% (or 16% rounded up)

Explanation:

Subtract the sale price from the original price first. This is the amount that was taken off.

$45-$38 = $7.00

To get the percentage, divide this discount amount by the original price.

$7.00/$45 = .155

Multiply by 100

.155 x 100 = 15.5%
