Question

the number of cheeseburgers sold was 2 times the number of hamburger

Answer 1

Answer:

137 hamburgers

Explanation:

Let us call h the number of hamburgers sold and c the number of cheeseburgers.

Now we are told that a combined 411 hamburgers and cheeseburgers were sold, meaning

$h+c=411$

Furthermore, we are also told that two times as many cheeseburgers were sold as hamburgers, meaning

$c=2h$

Now, the first step in finding the value of h is to substitute c = 2h in the first equation to get

$2h+h=411$$3h=411$

Dividing both sides by 3 gives

$h=\frac{411}{3}$$h=137$

which is our answer!

Hence, 137 hamburgers were sold.
