A one year membership to a gym Costa $725 the registration fee is $125 and the remaining amount la paid monthly define a variable then write and solve and equation to find how much new members pay each month

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.
