Question

At Silver Gym, membership is $20 per month, and personal training sessions are $35 each. At Fit Factor, membership is $40 per month, and personal training sessions are $25 each. In one month, how many personal training sessions would Sarah have to buy to make the total cost at the two gyms equal?

Answer 1

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

35 + 25N = 75 + 15N subtract 15N from both sides

35 + 10N = 75 subtract 35 from both sides

10N = 40 divide both sides by 10

N = 4
