How much will a membership cost a member by the end of one year if customers can sign up by paying a registration fee of $200 and a monthly fee of $39?

The problem asks you to solve for two aspects of a membership fee.
First you have a base rate of $200 then you will pay $39 per month for 12 months.

$200 + 12($39) = Annual Cost

$200 + $468 = Annual Cost

$668 = Annual Cost

This could actually be completed as a linear equation if the registration is a one time only charge.

F(x) = $39(n) + $200

Where n = the number of months an individual will remain as a member of the club.

You could graph this linearly on a coordinate grid with 200 as the y intercept and 39/1 as your slope.

y = mx + b
y = 39n + 200
