Final answer:
The Internal Rate of Return (IRR) of a project is the interest rate that makes the net present value of all cash flows (both positive and negative) from the project equal to zero. To find the IRR for Project Michelle, one would typically use a financial calculator or software, as manual calculations are complex and often not feasible.
Step-by-step explanation:
The Internal Rate of Return (IRR) is a financial metric used to assess the profitability of investments. To calculate the IRR for Project Michelle, we need to compare the present value of cash inflows to the initial outlay, and find the rate at which they are equal. However, calculating IRR often requires the use of financial calculators or software, as it involves solving for the rate in the net present value equation which typically cannot be done algebraically. The question does not provide a clear answer to the IRR, and it seems there's some unrelated information included.
Given the information, the student is expected to input the initial outlay and the subsequent cash inflows into an IRR calculator and solve for the interest rate that makes the net present value (NPV) of the project zero. Since we cannot compute it exactly without additional tools, the direct answer is not provided here.
