Mary purchased 4 tires by mail order. She paid $49.60 per tire plus $5.80 per tire for shipping and handling. There is no sales tax, because the tires were purchased out of state. She also had to pay $7.98 per tire for mounting and balancing. At a local store, Mary's total for the 4 tires with mounting and balancing would be $292 plus 7 % sales tax. How much did Mary save by purchasing the tires through the mail?
