A new one-year membership to a gym costs $720. The registration fee is $125, and the remaining amount is paid monthly. Define a

Finger [1]

So, the fee is 125 and...

125+

a certain fee "x"

125+x*

which is paid monthly, that is 12 times:

125+x*12

and this equals 720.
125+x*12=720

subtracting 125:

x*12=595
dividing by 12:
x=49,58

and this is how much they pay each month!
