Suzanne brought a sweater at the sale price of $25. the original cost of the sweater was $40. what percent represents the discount that suzanne received when buying the sweater?

So,

The percent discount is the amount of discount divided by the original price.  In formula that is:



The discount is the difference between the original price and the sale price.

40 - 25 = $15

The discount is $15.

Divide the discount by the original price.



To convert from decimal form to percent form just move the decimal point two places to the right and add a percent sign.

0.375 --> 37.5 --> 37.5%

So the percent discount on the sweater is 37.5%.
