May someone double check my work and show me the correct solutions. Will thumbs up

6. Understanding the NPV profile If mutually exclusive projects with normal cash flows are being analyzed, the net present value (NPV) and internal rate of return (IRR) methods agree. Projects W and X are mutually exclusive projects. Their cash flows and NPV profiles are shown as follows. If the weighted average cost of capital (WACC) for each project is 10%, do the NPV and IRR methods agree or conflict? The methods agree. The methods conflict. When there is a conflict, a key to resolving this it is the assumed reinvestment rate. The NPV calculation implicitly assumes that intermediate cash flows are reinvested at the modified internal rate of return (MIRR) , and the IRR calculation assumes that the rate at which cash flows can be reinvested is the As a result, when evaluating mutually exclusive projects, the is usually the better decision criterion
