1. Sam buys a pair of shoes and has a coupon for $15 off. The day he buys the shoes, the store has a sale offering 20% off the price of all shoes. a) Write a function to represent the cost, C, of a pair of shoes at price, p, if just the coupon reduction is applied to the cost off the shoes. Write a function that represents the cost, D, if just the discount is applied to the cost. b) What does the function D(C(p)) represent if a pair of shoes has a regular price of $80? Determine D(C(80)). c) What does the function C o D represent for a pair of shoes with a regular price of $80? Determine C o D for the same pair of shoes.
