NPV Versus Internal Rate of Return Nguyen Hospital is considering two different low-field MRI systems: the Clearlook System and the Goodview System. The projected annual revenues, annual costs, capital outlays, and project life for each system (in after- tax cash flows) are as follows: Assume that the cost of capital for the company is 8 percent. The present value tables provided in Exhibit 19B.1 and Exhibit 19B.2 must be used to solve the following problems. Required: 1. Calculate the NPY for the Clearlook System. 2. Calculate the NPY for the Goodview System. Which MRI system would be chosen? 3. What if Nguyen Hospital wants to know why IRR is not being used for the investment analysis? Calculate the IRR for each project. Round the discount factor to three decimal places. Round the IRR to the nearest whole percentage value (for example, 10.6% rounds to 11% and should be entered as "11" in the answer box.) Why IRR is not suitable for choosing among these mutually exclusive investments
