Alocal sporting goods manager gave each member of a basketball team a coupon for 20% off the regular price of one pair of basketball shoes.

part a:
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.

part b:
katie selected a pair of shoes for the regular price of $120. after the 20% off discount is applied, what will be the discounted cost of the shoes (before tax)? justify your answer using equations, models, and/or words to explain your mathematical reasoning.

Part A: To find the amount of the discount multiply the regular price by the amount of the discount:

80 x 20% = 80 x 0.20 = 16

The discount is $16

Part B:

20% off means she would be paying 80% of the original price ( 100% - 20% = 80%)

Multiply the regular price by 80%:

120 x 80% = 120 x 0.80 = 96

She will pay $96

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
