Answer: USD 3,060.29

The correct estimate of the prepayment amount for that month is USD 3,060.29. Prepayment for any given month is defined as the "principal payment" in excess of the "scheduled principal payment" and is computed as the month's total payment, less the month's scheduled interest payment, less the month's scheduled principal payment. Alternatively, it can be calculated as the month's total payment, less the month's scheduled total payment. To compute the scheduled total payment, consider an amortizing fixed-rate loan with the following particulars: Present Value (PV) = 1,750,000; Number of Payments (N) = 12 x 30 = 360; Future Value (FV) = 0; Interest Rate per Period (1/Y) = 8%/12 = 0.67. Using a financial calculator, the scheduled total payment per month (PMT) is calculated to be 12,889.71. Therefore, the prepayment in the specified month is calculated as the total payment made (USD 15,950.00) minus the scheduled total payment (USD 12,889.71), which equals USD 3,060.29. The other options provided are incorrect for the following reasons: - Option B (USD 4,933.62) is the total payment less the scheduled interest payment for the month, which is incorrect because it includes the scheduled principal payment. - Option C (USD 11,016.38) is the scheduled interest payment for the month, calculated as 0.0067 x the beginning balance of USD 1,644,235.78. - Option D (USD 14,076.60) is the total payment made less the scheduled principal payment for the month, which is incorrect because it includes the scheduled interest payment.
