Question

A local hamburger shop sold a total of 481 hamburgers and cheeseburgers on Wednesday. There were 69 fewer cheeseburgers sold than hamburgers. how many hamburgers were sold on wednesday?

Answer 1

275

Explanation:

t = total sold

c = cheeseburgers h = hamburgers

c + h = t total is equal to cheeseburgers + hamburgers

we know that

c + h = 481

and that c = h - 69

so we can rewrite the first equation as

(h-69) + h = 481

2h = 481 + 69

2h = 550 h=550/2=275

so there 275 hamburgers were sold
