Question

Membership at the YMCA costs $15 per month plus $80 to sign-up. Blink costs $29 per month but is free

to sign-up. After how many months will the two gyms cost the same amount?

Answer 1

43 months in ymca including the $80 sign up fee is equal to 25 months in blink

Explanation:

$725 divided by $29 =25 months

$ 725 - $80 sign up = $645 .

Now we divide this by $15.

$645 divided by 15= 43 months

Answer 2

Let months be x

`\\ \sf\longmapsto 80+15x=29x`

`\\ \sf\longmapsto 29x-15x=80`

`\\ \sf\longmapsto 14x=80`

`\\ \sf\longmapsto x\approx 6months`
