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. When , if ever, is the cost the same?

Answer 1

5 months will be the same cost at each gym.

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`

`(-5x)/(-5)=(-25)/(-5)`

`x=5`

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