On Thursday, a local hamburger shop sold a combined total of 417 hamburgers and cheeseburgers. The
number of cheeseburgers sold was two times the number of hamburgers sold. How many hamburgers were
sold on Thursday?

Respuesta :

Let H represent Hamburgers.  

Let cheeseburgers represent 2H .

H + 2H = 417

3H = 417

H = 417/3

H = 139 hamburgers  

2H = 2 * 139 = 278 cheeseburgers

Therefore, there were 139 hamburgers sold on Thursday.
