Anna wants to take fitness classes. She compares two
gyms to determine which would be the best deal for her.
Fit Fast charges a set fee per class. Stepping Up
charges a monthly fee, plus an additional fee per class.
The system of equations models the total costs for each.

y = 5.5x + 10
1. Substitute: 7.5x = 5.5x + 10
How many classes could Anna take so that the total
cost for the month would be the same?

What is the total monthly cost when it is the same for
both gyms?
