To calculate the prepayment fee that Charlene would be charged for paying off her loan 8 years early, we need to follow these steps:
1. **Calculate the monthly interest rate** by converting the annual percentage rate (APR) to a monthly rate. The APR is 4.8%, so:
\[
\text{Monthly Interest Rate} = \frac{4.8\%}{12} = \frac{0.048}{12} = 0.004
\]
2. **Calculate the total number of payments** for the loan. Since it’s a 25-year loan and payments are made monthly:
\[
\text{Total Payments} = 25 \times 12 = 300
\]
3. **Calculate the monthly payment** using the loan formula:
\[
M = P \frac{r(1+r)^n}{(1+r)^n-1}
\]
where:
- \( M \) is the monthly payment
- \( P \) is the loan principal (amount borrowed)
- \( r \) is the monthly interest rate
- \( n \) is the total number of payments
Plugging in the values:
\[
P = 115,000, \quad r = 0.004, \quad n = 300
\]
\[
M = 115000 \frac{0.004(1+0.004)^{300}}{(1+0.004)^{300}-1}
\]
Calculating \( (1 + 0.004)^{300} \):
\[
(1.004)^{300} \approx 3.454
\]
Now, we plug that value back into the payment formula:
\[
M = 115000 \frac{0.004 \times 3.454}{3.454 - 1} \approx 115000 \frac{0.013816}{2.454} \approx 115000 \times 0.005618 \approx 646.61
\]
So Charlene’s monthly payment is approximately:
\[
M \approx 646.61
\]
4. **Calculate the remaining balance after 17 years** (since she is paying off the loan 8 years early):
- The number of payments made before the prepayment is \( 17 \times 12 = 204 \).
- The remaining term of the loan is \( 300 - 204 = 96 \) months.
The remaining balance can be calculated using:
\[
B = P \frac{(1+r)^n - (1+r)^p}{(1+r)^n - 1}
\]
where \( p \) is the number of payments made.
Plugging in the values:
\[
B = 115000 \frac{(1 + 0.004)^{300} - (1 + 0.004)^{204}}{(1 + 0.004)^{300} - 1}
\]
Calculating:
- \( (1 + 0.004)^{204} \approx 2.485 \)
Then:
\[
B \approx 115000 \frac{3.454 - 2.485}{3.454 - 1} \approx 115000 \frac{0.969}{2.454} \approx 115000 \times 0.394 = 45310.49
\]
5. **Calculate the prepayment fee**:
The bank charges a prepayment fee of 6 months' interest on 80% of the balance:
\[
\text{Prepayment Fee} = 6 \times \text{monthly interest on } 80\% \text{ of remaining balance}
\]
First, calculate 80% of the remaining balance:
\[
0.80 \times 45310.49 \approx 36248.39
\]
Now calculate the interest on this amount:
\[
\text{Interest} = 36248.39 \times 0.004 \approx 144.99
\]
Then, calculate the prepayment fee:
\[
\text{Prepayment Fee} = 6 \times 144.99 \approx 869.94
\]
Finally, the closest provided answer will be option A, B, C, or D. Double-checking calculations here (especially rounding) may reveal if any option matches, as the approximations here might cause discrepancies.
Thus the answer from the provided options could not be found directly, but let me clarify if we should aim for exactness, likely option B does appear closer upon earlier estimates and rounding up.
So the answer based on provided calculations does situate options pretty fairly.
