konstantin123 [22]

Heyo. Let's go ahead and set this problem up

It should look like this

12x + 125 = 725

The variables can be another letter, doesn't matter.

12 will stand for the months in a year

x is the amount paid per month

125 is the registration free

725 is the one year membership total


Subtract both sides by 125 to get:

12x = 600

Divide both sides by 12 to get:

x=50

That being said, each month, a new member will pay $50.
