Question

At Silver Gym, membership is $30 per month, and personal training sessions are $35 each. At Fit Factor, membership is $60 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: 5 personal training sessions

Explanation:

Given only 1 month, then set the 2 equations equal to each other, given that x=# of personal training sessions:

25+45x = 75 + 35x

-25-35x -25-35x

So, 10x=50; divide both sides by 10, to get:

5, so, 5 personal training sessions per month to make the 2 costs equal to one another.
