Betty bought a new dress for 30% off. The original price of the dress was 45 dollars. How much was the sale price?

A. $40.00

B. $35.50

C. $31.50

D. $27.00

What you first need to do is multiply $45 by 0.30. The 0.30 is from the total percent off. Once you get this number, that is your total saved money. You must subtract this total from $45 to get your final answer. It should look something like this:

$45 (0.30) = $13.5

$45 - $13.5 = final answer

It'll Most Likely Be ... C. $31.50
