A store has issued two different coupons for its customers to use. One coupon gives customers $25 off their purchase price, and the other coupon
gives customers 30% off of their purchase. The store allows customers to use both coupons and choose which coupon to apply first. For this
context, ignore sales tax.
Let f be the function that inputs a cost (in dollars) and outputs the cost after applying the "$25 off" coupon, and let g be the function that inputs
a cost (in dollars) and outputs the cost after applying the "30% off" coupon.
a. A customer purchases an item for $110 and asks the cashier to apply the "$25 off" coupon first, followed by the "30% off" coupon. What
is the cost of the item after the two coupons are applied?
