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

X= cost of shoes before discount

100-20=80

.80x = x-15

.80x-x= -15

-0.2x= -15

X= 75 dollars
