Mary purchased 4 tires by mail order. She paid $54.60 per tire plus $5.30 per tire for shipping and handling. There is no sales tax, because the tires were purchased out of state. She also had to pay $8.81 per tire for mounting and balancing. At a local store, mary’s total for the 4 tires with mounting and balancing would be $304 plus 8% sales tax. How much did Mary save by purchasing the tires through the mail?
