Question

Joaquin is ordering 5 identical sandwiches and a bag of chips. The bag of chips cost $1.25 and the entire order costs $38.75. Write an equation you can use to find the price of the sandwhich. Let’s represent the price of the sandwhich.

Answer 1

A sandwich costs $7.5

Explanation:

Given

Represent chips with c and sandwiches with c

`c = \$1.25`

`Total = \$38.75`

From the question, we understand that 5 sandwiches were ordered.

Hence, the question of the system is:

`5s + c = Total`

Substitute values for Total and c

`5s + 1.25 = 38.75`

Collect Like Terms

`5s = 38.75 - 1.25`

`5s = 37.5`

Divide both sides by 5

`s = (37.5)/(5)`

`s = 7.5`
