Final answer:
The present value of the investment project at 11%, 10%, and 9% interest rates are $10.24 million, $10.45 million, and $10.63 million, respectively. At all these interest rates, the present value exceeds the initial investment cost of $10 million, suggesting the project is financially viable at each rate.
Step-by-step explanation:
To calculate the present value (PV) of the investment project, we use the formula PV = FV / (1 + r)^n, where FV is the future value, r is the interest rate, and n is the number of time periods. Here, FV is $15 million, and n is 4 years.
(a) At 11% interest rate:
PV = $15 million / (1 + 0.11)^4 = $15 million / 1.4641 = $10.24 million.
Since the PV at 11% ($10.24 million) is greater than the investment cost ($10 million), the firm should undertake the project.
(b) At 10% interest rate:
PV = $15 million / (1 + 0.10)^4 = $15 million / 1.4641 = $10.45 million.
Since the PV at 10% ($10.45 million) is greater than the investment cost, the project is more favourable.
(c) At 9% interest rate:
PV = $15 million / (1 + 0.09)^4 = $15 million / 1.4116 = $10.63 million.
With a PV of $10.63 million at a 9% interest rate, the project is still feasible as it exceeds the cost of the investment.
