Answer

Answer:

Total cost of Silver Gym = 35 + 25N

where N

is the number of sessions

Total cost of Fit Factor = 75 + 15N

To find out when the costs are equal....set the

equations equal

subtract 15N from both

35 + 25N = 75 + 15N

sides

35 + 10N = 75

subtract 35 from both sides

10N = 40

divide both sides by 10

N = 4
