Answer:
Step-by-step explanation:
$85 joining fee (this will be added to the equation because it is a flat fee and will not change, it is also just a one time fee)
20x + 85
Its $20 a month plus $85
You will plug in the month amount to x and solve.
How much has she paid after six months?
20(6) +85
= 120 +85
= 205
Courtney will have paid $205 after six months
