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 = 7.5x
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?
