Tamora’s total finance charge was $3,403.53 if Tamora paid in addition of $939.25 in service charges option (c) is correct.
It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We have:
Principal amount(Loan principal) = $10,675
Interest rate  = 4.75 %
Monthly rate = 4.75/12% ⇒0.39583% ⇒ 0.00395
Additional amount she paid in service charge = $939.25
Number of months = 9×12 = 108 months
We can find the total finance charge as follows:
Finance charge = Total amount repaid +service charge - Loan principal
The formula for the monthly payment of the loan is given by:
[tex]\rm Monthly \ payment = \frac{Loan \ principal }{\frac{(1-(1+r)^-^n)}{r} }[/tex]
[tex]\rm Monthly \ payment = \frac{10675}{\frac{(1-(1+0.00395)^-^{108})}{0.00395} }[/tex] Â Â
After calculating, we get:
Monthly payment = $121.66
For 108 months, Tamora paid:
= 121.66×108
= $13,139.23
The finance charge will be:
= $13,139.23+$939.25-$10,675
= $3,403.53
Thus, Tamora’s total finance charge was $3,403.53 if Tamora paid in addition of $939.25 in service charges option (c) is correct.
