(Calculating MIRR) The Dunder Muffin Company is considering purchasing a new commercial oven that costs $380,000. This new oven will produce cash inflows of $170,000 at the end of Years 1 through 10. In addition to the cash inflows, at the end of Year 5 there will be a net cash outflow of $250,000. The company has a weighted average cost of capital of 11.8 percent. What is the MIRR of the investment? Would you make the investment? Why or why not? Note that we discounted the project's negative cash flows back to the present using the project's required rate of return and then computed the MIRR from the modified cash flows.
