Final answer:
The IRRs for Projects A and B cannot be accurately determined from the information given, as the figures presented appear to be errors. The IRR rule suggests investing in the project with the higher IRR, but the best investment also depends on other factors like scale, risk, and strategic fit.
Step-by-step explanation:
To calculate the internal rate of return (IRR) for projects A and B, we need to solve for the discount rate that sets the net present value (NPV) of the cash flows to zero. The cash flows given are:
- Project A: -30,000, +21,000, +21,000
- Project B: -50,000, +33,000, +33,000
The stated IRRs are $6,446 for project A and $7,273 for project B, but these numbers do not actually represent the IRR. They seem to be typos or errors in the question. The IRR would typically be expressed as a percentage, not a dollar amount.
Based on the IRR rule, the project with the higher IRR would be considered better, assuming other factors are equal. However, the 'best' project also depends on other considerations such as the scale of investment, risk, strategic fit, and the time value of money. The IRR must be compared to the project's required rate of return or the company's hurdle rate to make a proper investment decision.
If the question intended to reference actual IRRs, further clarification would be needed to perform the calculation accurately and to compare the projects correctly.
