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 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?
