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.

Saved Price = $16

Step-by-step explanation:

Coupon Discount Percentage = 20%

Regular Price = $80

Therefore, Coupon Discount = 20% of 80

                                                 = .0.20 × 80

                                                  = $16

So, Price to be paid = 80 - 16

                                 = $64

So, Saved Price = 80 - 64

                            = $16

Therefore, if the original price is $80 and a 20% off coupon is used, Tonya will save $16 and will only have to pay $64.
