A local hamburger shop sold a combined total of 581 hamburgers and cheeseburgers on friday. there were 69 fewer cheeseburgers sold than hamburgers. how many hamburgers were sold on friday?
You need two equations: h + c = 581 h - 69 = c Substitute (h - 69) for c in the first equation: h + (h - 69) = 581 Solve: 2*h = 581 + 69 2*h = 650 h = ?
