This problem may look hard, but it is really just what we have been doing already!
Our equation is:
$0.09x -5 = 365$. The 5 is the one time fee. The 0.09 is the rate (or derivative). The 365 is the total earned.
First, we should add 5 to both sides.
$0.09x = 370$
Then, we should divide both sides by 0.09.
$x = 4111$
