Answer 1

Hi Nicole-

Instead of giving you the answer, I'd like to give you a similar question with different numbers.

$8 per session to rollerblade, $6 per session for safety equipment rental, $115 new rollerblades, $227 total.

Define variables:X 

X = number of rollerblading sessions

Write an equation that can be used to find the number of sessions: 

Reason: For each session, you need to pay to rollerblade and pay for renting the safety equipment. 

So each session costs:

8X + 6X

You have a 1-time expense of $115 for the new rollerblades.

So the equation is:

8X + 6X + 115 = 227

Combine like terms.

14X + 115 = 227

Combine line terms.

14x = 112

Solve for X

X = 8

He took 8 rollerblading sessions.

Does that help you?

Best regards.

Bob
