Final answer:
The student's question revolves around calculating NPV, payback period, Profitability Index, and IRR to evaluate a business investment. Recommendations are given preference to NPV because it provides a comprehensive view of the project's value over time. The IRR method is used to decide whether to proceed with an add-on investment to existing products.
Step-by-step explanation:
The question involves calculating various financial metrics to assess the viability of a business investment project, including Net Present Value (NPV), payback period, Profitability Index, and Internal Rate of Return (IRR). The NPV calculation involves discounting future cash flows back to their present value using the company's cost of capital, which in this case is 11%. The payback period is the time it takes for an investment to generate cash flows to recover the initial investment costs. The Profitability Index is a ratio that compares the present value of future cash flows to the initial investment. Lastly, the IRR is the discount rate at which the NPV of an investment is zero, and it's used to evaluate the attractiveness of a project.
To provide recommendations to the boss, we would likely suggest using the NPV method as it measures the absolute value created by the investment and takes into account the time value of money, which is a crucial component in investment decisions. As for the add-on investment to the tanks and the IRR calculation, we would analyze the cash flows and discount rates to determine whether the project's IRR exceeds the company's required return, thereby deciding if it should be accepted.
