A math book at the Victor Valley College bookstore originally cost $60 is on sale for $36. What is the rate of discount?

Answer 1

First find the amount of the discount. That would be 60 - 36 or $24.

Now to find the percentage rate of the discount, take the amount of the discount ($24) and divide by the original amount ($60):

24/60 = 0.4

To turn 0.4 into a percent, multiply it by 100 (or move the decimal over two places) to get 40%

Answer 2

$60(1-discount) = $36

Solve for discount. The answer will be in decimal form. Multiply the discount by 100% to put into percent form.
