You and a friend sign up for a health club. It costs $50 to join, plus $20 a month. However, the first 100 customers can sign up for $30, plus $20 a month. Your friend is customer 100, and you are 101.
If the accumulated cost for each membership were graphed, what would it look like? What would the difference be between your accumulated cost and your friend's accumulated cost at any given month?

Hello!

First you have to find the differences in the prices

The only difference is that your friend signed up for $30 and you signed up for $50

This means that the lines would be parallel and your cost will be $20 higher than your friends

The answer is $20

Hope this helps!
