Final answer:
The monthly payment for a $80,000 mortgage loan at 6% interest over 25 years is approximately $479.65, which corresponds to option C. This is calculated using the standard formula for the monthly payment of an amortizing loan.
Step-by-step explanation:
To determine the monthly payment for a fully amortized mortgage loan, the loan amount, interest rate, and term of the loan must all be taken into consideration. The question asks for the monthly payment of an $80,000 mortgage loan with a 6% annual interest rate, compounded monthly, over 25 years. To calculate this payment, one would typically use the formula for the monthly payment (M) on an amortizing loan, which can be expressed as:
M = P [i(1 + i)^n] / [(1 + i)^n - 1]
Where:
P = principal loan amount
i = monthly interest rate
n = number of payments
The monthly interest rate is the annual rate divided by 12 months, which for a 6% annual rate yields 0.06/12 = 0.005. The total number of payments for a 25-year loan with monthly payments is 25 * 12 = 300.
After substituting the given values into the formula, we can calculate the monthly payment. However, as this calculation is complex and would typically be performed with a financial calculator or software, we are given answer options. By using financial software or a calculator and performing the calculation, one can find that the correct monthly payment is closest to option C) $479.65.
