Question

On Friday, a local hamburger shop sold a combined total of 252

Answer 1

Answer: 84  hamburgers were sold on Friday.

Step-by-step explanation:

Let be "x" the number of hamburguers sold on Friday.

Knowing that the number of cheeseburgers sold was two times the number of hamburgers sold, this can be represented with:

$y=2x$

Then, we can write the following expression:

 $x+y=252$

Substituting $y=2x$:

$x+2x=252$

And finally solving for x:

$3x=252\\\\x=\frac{252}{3}\\\\x=84$

So, 84  hamburgers were sold on Friday.

Answer 2

Answer:

84 hamburgers

Step-by-step explanation:

We are given that a total of 252 hamburgers and cheeseburgers were sold at a shop.

Given that the number of cheeseburgers sold was two times the number of hamburgers sold, we are to find the number of hamburgers sold.

Assuming $x$ to be the number of hamburgers and $y$ yo be the number of cheeseburgers:

$x+y=252$

Cheeseburgers = 2 (hamburgers)

$y=2x$

$x+2x=252$

$3x=252$

$x=84$

Therefore, 84 hamburgers were sold on Friday.
