Your grandmother, who recently passed away, left you a legacy of $ 1,000,000 and advised you to make an industrial investment with her desire. Upon this, as a result of your feasibility study, you have determined that the XYZ investment is suitable; because you will also be able to benefit from government incentives. The feasibility study has also shown that your project, with an economic life of 5 years, provides $ 200,000, 250,000, 350,000, 450,000 and $ 400,000 cash flows annually and a scrap value of $ 200,000 at the end of its economic life. Assuming the required rate of return is 10%, calculate the discounted payback period and internal rate of return of your project.

Before starting the calculation, briefly summarize in a few sentences in which industry and where you make the investment and why you prefer this sector. Use the discount factors to discount cash- flow and clearly show your transactions.
