Solution
Solution Steps
Step 1: Calculate the monthly interest rate
The annual interest rate is \(9\%\). To find the monthly interest rate, divide the annual rate by 12:
\[
\text{Monthly interest rate} = \frac{9\%}{12} = 0.75\% = 0.0075.
\]
Step 2: Calculate the finance charge
The finance charge is the interest accrued on the principal for one month. Multiply the principal by the monthly interest rate:
\[
\text{Finance charge} = \$13,700 \times 0.0075 = \$102.75.
\]
Step 3: Calculate 2% of the principal
The minimum payment includes 2% of the principal. Calculate this as:
\[
2\% \text{ of principal} = 0.02 \times \$13,700 = \$274.00.
\]
Step 4: Calculate the total minimum payment
Add the finance charge and 2% of the principal to get the total minimum payment:
\[
\text{Minimum payment} = \$102.75 + \$274.00 = \$376.75.
\]
Final Answer
This month's minimum payment is \(\boxed{\$376.75}\).
