A gym membership at one gym costs $10 every month plus a one-time membership fee of $15, and a gym membership at another gym cost $4every month plus a one-time $40 membership fee. What's the amount after 4 months?

Let us assume that the number of months after which

the gym memberships will cost the same = x

Then

15 + 10x = 40 + 4x

10x - 4x = 40 - 15

6x = 25

x = 25/6

 = 4 1/6

So the membership fee of both the gyms will become same after 4 1/6 months. You can also consider that as after 5 months the membership fees of both the gyms will become same. I hope the procedure is not very complicated for you to understand.
