Question

348 hamburgers and cheeseburgers were sold on Tuesday. The number of cheeseburgers sold was 3 times the number of hamburgers sold. How many hamburgers were sold?

Answer 1

There were 261 Cheeseburgers and 87 Hamburgers sold on Tuesday

Explanation:

Let's write some equations where H=Hamburgers and C=Cheeseburgers:

1) H+C=348

2) C=3H

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

3H+H=348

2) Combine alike terms:

4H=348

3) Divide both sides by 4:

H=87

4) Now, substitute 87 as H in the first equation:

87+C=348

5) Subtract 87 from both sides:

C=261
