Final answer:
The correct monthly installment payment on a $300,000 loan at an 8% annual interest rate over a 15-year period is $2,866.96, which is option a.
Step-by-step explanation:
The student is asking about the calculation of a monthly installment payment on a mortgage. To calculate the monthly payment of a $300,000 loan at an 8% annual interest rate, compounded monthly, over a 15-year period, we need to use the formula for an annuity. The formula for the monthly payment R on a mortgage is:
R = P [i (1+i)^n] / [(1+i)^n - 1]
Where:
- P is the principle amount ($300,000)
- i is the monthly interest rate (8%/12 = 0.0066667)
- n is the total number of payments (15 years * 12 months/year = 180 payments)
Using this formula, we can calculate the exact monthly installment payment that would be required.
Without showing detailed calculations here (which require a financial calculator or an amortization formula in a spreadsheet or financial software), we can find the closest option to the calculated result among the provided choices.
The correct answer is option a) $2,866.96.
