Question

Tonya selected a pair of shoes for the regular price of $80. How much money will she save by using the 20% off coupon? Justify your answer using equations, models, and/or words to explain your mathematical reasoning.
Answer:

Answer 1

20 percent off of 80 should be 16. So 80-16 = 64.

She paid $64 for a $80 pair of shoes. 

(Side note- $80 for shoes is a lot!) 

She saved $16

Answer 2

First convert the 20 percent into decimal form
to do this, divide by 100

20/100= .2

now multiply this .2*80 to find the money saved

.2*80= $16 saved
