Question

A local hamburger shop sold a combined total number of 379 and cheeseburgers on Friday. There were 71 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Friday

Answer 1

225 hamburgers

Explanation:

We call h the number of hamburgers and we call s the number of hamburgers with cheese

We know that in total 379 cheeseburgers sold and hamburgers were sold.

This means that:

`h + s = 379`

We also know that There were 71 fewer cheeseburgers sold than hamburgers

This means that:

`s = h-71`

Now we substitute the second equation in the first and solve for h.

`h+h-71=379\\\\2h=379+71\\\\h=(450)/(2)\\\\h=225`
