Question

On Thursday, a local hamburger shop sold a combined total of 327 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the number of hamburgers sold. How many hamburgers were sold on Thursday?

Answer 1

The number of hamburgers is 109.

Explanation:

Let h = number of hamburgers

Let c = number of cheeseburgers

The total number sold gives us the equation below.

h + c = 327

"The number of cheeseburgers sold was two times the number of hamburgers sold.

This gives us the equation

c = 2h

Now we substitute c with 2h in the first equation and solve for h.

h + 2h = 327

3h = 327

h = 109

The number of hamburgers is 109.
