Question

on tuesday, a local hamburger shop sold a combined total of 336 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number or hamburgers sold. how many hamburgers were sold on tuesday?

Answer 1

84 hamburgers!

(and 252 cheeseburgers -optional-)

Explanation:

Write the following equations based on the problem:

H+C=336 <-- "combined total of 336"

C=3H <-- "the no. of Cheeseburgers sold was three times the no. of hamburgers"

1) Substitute 3H as C in the 1st equation:

H+3H=336

2) Combine alike terms:

4H=336

3) Divide both sides by 4:

H=84

Answer 2

4x=336

x=84

3x=252

Hope it helps!
