A firm is considering the two mutually exclusive investments projects. Project Alpha requires an initial outlay of $600 and will return$160 per year for the next seven years; Project Beta requires an initial outlay of $1,100 and will return$350 per year for the next five years. Assuming a 11% required return, calculate the NPV, Payback Period, and MIRR of each project. Please help by showing Excel calculations. Thanks!
