Question

Clare has a scratch-off coupon to be used on one pair of shoes. If the original price of the shoes is `\$87.50` and she pays `\$70`, what percent off does she receive with her coupon?

Answer 1

Clare received approximately 20% off on the pair of shoes using her scratch-off coupon. This was calculated using the formula for percent change.

Step-by-step explanation:

The question is asking about the

percentage off

that Clare received with her scratch-off coupon. This can be solved using the formula for percent change which is the difference between the two amounts (original price and paid price) divided by the original price, then multiplied by 100. In this case, the original price of the shoes is

$87.50

and Clare paid

$70

. The difference between these two prices is $87.50 - $70 = $17.50. To find the percentage off, divide the difference, $17.50 by the original price, $87.50, and multiply by 100. Doing the math, you would get approximately

20%

-off.
