Answer 1

First apply  20% discount  then applied $15 coupon combination gives better deal.

As given in the question,

Let final cost of the shoes be $100

First apply $15 coupon  then applied 20% discount

100-15=$85

Now,  20% of 85= (20/100) × 85

                          =$17

Final price,  85 - 17 =$68

First apply  20% discount  then applied $15 coupon

Now,  20% of 100= (20/100) × 100

                          =$20

100-20 = $80

Apply coupon $15

Final price, 80 - 15 =$65

Therefore, first apply  20% discount  then applied $15 coupon combination gives better deal.
