F inverse? then :
let's consider 3x + 9 as y.
so :

Given that Dan bought a home theater system for $178.99 on the installment plan, and the terms of the contract is such that he will pay $35 in 6 months.
The total amount he paid by the end of the term will be:
amount=(monthly payment)*(number of months)
=35*6
=$210
b] Dan's Finance charge will be given by:
(total amount he paid)-(price of home theater)
=210-178.99
=$31.01
