Question

The total bill of a meal at a restaurant is 25x – 115. Five friends agree to split the cost of the meal equally. What could you do to find the amount that each person must pay? Explain.

Answer 1

Greetings!

Explanation:

If 25x - 115 is the total amount, then this needs to be divided by 5:

`(25x - 115)/(5)`

This division can also be written like:

`(25x)/(5) + (115)/(5)`

Which gives the result of:

5x + 23 , which is the amount that each person must pay.

Hope this helps!

Answer 2

Sample Response: Factor the GCF of five out of the total bill. Divide both terms of the expression by 5. The result is 5x - 23, which is the expression that can be used to find the amount each person pays.

Check all that you included in your response:

Use 5 as the GCF for the total bill.

Divide both terms by 5.

The expression 5x - 23 can be used to find the amount each person pays.

Explanation:

25x - 115

5 (5x - 23)

each person pays 5x -23
