The annual interest rate your firm is paying for the $275,000 loan, repaid in five annual installments of $76,300, is approximately 12.01 percent.
Option c is correct.
The problem can be solved using the Present Value (PV) formula:
PV = PMT * (1 - (1 / (1 + r)^n)) / r
Where:
PV is the present value of the loan ($275,000)
PMT is the annual payment ($76,300)
n is the number of payments (5 years)
r is the annual interest rate (unknown)
We need to rearrange the formula to solve for r:
r = (1 - (PV / PMT)) / (1 - (1 / (1 + r)^n))
Plugging in the values:
r = (1 - (275,000 / 76,300)) / (1 - (1 / (1 + r)^5))
Solving for r using iterative methods (like trial and error or numerical solvers) gives the answer:
r ≈ 12.01%
Therefore, your firm is paying an annual interest rate of approximately 12.01%.
Option c is correct.
