Obtain the value of h: From the APR table, find the value of h corresponding to the given APR and the number of monthly payments.
Calculate unearned interest: Use the actuarial method formula to calculate the unearned interest.
Calculate the payoff amount: Subtract the unearned interest from the total amount due to find the payoff amount.
Step 1: Obtain the Value of \( h \)
From the APR table, for \( \text{APR} = 6.0\% \) and \( n = 24 \) monthly payments, we find:
\[
h = 6.37
\]
Step 2: Calculate the Unearned Interest
Using the actuarial method, the unearned interest is calculated as:
\[
\text{Unearned Interest} = \frac{n \cdot \text{monthly payment} \cdot h}{100}
\]
Substituting the values:
\[
\text{Unearned Interest} = \frac{24 \cdot 433.49 \cdot 6.37}{100} = 662.72
\]
Step 3: Calculate the Total Amount Due
The total amount due is given by:
\[
\text{Total Amount Due} = n \cdot \text{monthly payment} = 24 \cdot 433.49 = 10403.76
\]
Step 4: Calculate the Payoff Amount
The payoff amount is calculated by subtracting the unearned interest from the total amount due:
\[
\text{Payoff Amount} = \text{Total Amount Due} - \text{Unearned Interest} = 10403.76 - 662.72 = 9741.04
\]
