Question

At Silver Gym, membership is $20 per month, and personal training sessions are $35 each. At Fit Factor, membership is $50 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

Hey,sup!

As per the question,

At silver gym, membership fee=20$.
Personal training=35$each.

At fit factor, membership fee=50$.
Personal training=25$each.

We can see silver gym's personal training fee is 10$ extra and membership fee is 30$ short.So let the number of personal training session be x.

So, 20+35x=50+25x.
=> 35x-25x=50-20.
=> 10x= 30.
=> x=30/10.
=> x= 3.

So Sarah would have to buy 3 personal training sessions to make the total cost at two gym's equal.

Hope it helps.
