Question

On Tuesday, a local hamburger shop sold a combined total of 441 hamburgers and cheeseburgers. The number of cheese burgers sold was two times the number of hamburgers sold. How many hamburgers were sold on Tuesday?

Answer 1

N = 441 = total number of hamburgers and cheeseburgers sold on Tuesday. It is given that # cheeseburgers = 2 x # hamburgers.

Let H = hamburgers sold. Then 441 = H + 2H, where 2H = # cheeseburgers sold.

Simplifying, 441 = 3H, thus H = 441/3 = 147 hamburgers sold on Tuesday.

Answer 2

x+2x=441

3x=441

x=147

hb=147
