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?

Five dinosaurs go for a walk and come across some lovely chicken wings. their names are rexy, bronto, steggy, paly, and terry. there are exactly 5 dozen wings(equal enough for each dino to have a dozen right? ); however, terry is on a diet and he only eats 6 wings. if paly eats 2 more than terry, steggy eats 4 more than paly, and bronto and rexy eat the same amount because they are really hungry from not eating all day, how many chicken wings did each dino eat?
