Question

With the 20% off coupon, Alexis received a discount of $15 on her shoes. What was the regular price of her shoes before the 20% off coupon was applied? Justify your answer using equations, models, and/or words to explain your mathematical reasoning. Answer

Answer 1

In this question, Alexis got 20% discount which was equal to $15 cut from the shoes original price. If $15 is 20% of the original price, then the full original price before the discount would be:

$15=20%

Original price= 100% * $15/20%=5* $15= $75
