store has issued two different coupons
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 D be the function that inputs a cost (in dollars) and outputs the cost after applying the "$25 off" coupon, and let P be the function that inputs a cost (in dollars) and outputs the cost after applying the "30% off" coupon.
1.A customer purchases an item for $140 and asks the cashier to apply the "$25 off" coupon first, followed by the "30% off" coupon. Use function notation to represent the cost of the item (in dollars) after the two coupons are applied.
