Astore has issued two different coupons for its customers to use. one coupon gives customers $20 off their purchase price, and the other coupon gives customers 20% 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 "$20 off" coupon, and let g be the function that inputs a cost (in dollars) and outputs the cost after applying the "20% off" coupon. a customer purchases an item for $130 and asks the cashier to apply the "$20 off" coupon first, followed by the "20% off" coupon. what is the cost of the item after the two coupons are applied?
