7) Considering Two Different Projects. An investor is considering two different projects. Project 1 requires an initial investment of $75 and returns $100 at the end of 1 year. Project 2 requires an initial investment of $150 and then returns $100 at the end of 1 year and another $100 at the end of 2 years. (a) Calculate the internal rate of return on Project 1. (b) Suppose for discounting the investor's interest rate is 8% per year. Calculate the present value of Project 2. Do the same for Project 1. (c) Which project would you choose first if you used the maximize NPV rule? What about if your objective is to shorten the payback period? Lastly, what if you use the Profitability Index or the BC Ratio to guide your decisions
