Nolan is considering buying stamps online. Stamps cost 49 cents each and are sold in books of 20 stamps. Each order has a $1.30 handling charge added to the cost of the stamps. The stamps cost the same at Nolan's local post office, but he will have to drive there, which creates a cost. Assume that gas costs $3.22 per gallon and the dis- tance to the post office from his office is 15 miles. If Nolan's truck gets 16 miles per gallon, is it cheaper for him to buy the stamps online or make the round trip to buy them
