Question

A local hamburger shop sold a combined total of 519hamburgers and cheeseburgers on Sunday.There were 69 more cheeseburgers sold than hamburgers. How many hamburgers were sold on Sunday?

Answer 1

C= 69 + H

C+H = 519

69+H + H = 519

2H = 519-69 = 450

H = 450/2 = 225 hamburgers sold on Sunday

C = 225+69 = 294 cheeseburgers sold on Sunday

225+294 = 519 total
