Natasha2012 [34]

Answer:

5 months will be the same cost at each gym.

Step-by-step explanation:

As

Exercise Plus charges a yearly fee of $75 plus $10 a month.

Gym and Swim charges a yearly fee of $50 plus $15 a month.

Let $x$ by the number of months

$75+10x=50+15x$

$10x=15x-25$

$-5x=-25$

$\frac{-5x}{-5}=\frac{-25}{-5}$

$x=5$

Therefore, 5 months will be the same cost at each gym.
