Question

on thursday, a local hamburger shop sold a total of 388 hamburgers and cheeseburgers. The number of cheeseburgers sold was bree times the number of hamburgers sold. How many hamburgers were sold on Thursday?

Answer 1

There were 97 hamburgers sold on Thursday

Step-by-step explanation:

The given is:

• On Thursday, a local hamburger shop sold a total of 388 hamburgers and cheeseburgers
• The number of cheeseburgers sold was three times the number of hamburgers sold

We need to find how many hamburgers were sold on Thursday

Assume that the number of hamburgers was sold is x

∵ The number of hamburgers sold is x

∵ The number of cheeseburgers sold was three times the number

   of hamburgers sold

- Multiply x by three to get the number of the cheeseburger

∴ The number of cheeseburger sold is 3x

∵ The shop sold a total of 388 hamburgers and cheeseburgers

- Ad x and 3x, then equate the sum by 388

∴ x + 3x = 388

- Add like terms in the left hand side

∴ 4x = 388

- Divide both sides by 4

∴ x = 97

There were 97 hamburgers sold on Thursday
