An investor has developed projections for an investment that will generate the following stream of future cash flows: Year 1 = $50; Year 2 = $60; Year 3 = $75; Year 4 = $80; Year 5 = $90. She believes she can invest her money at a rate of 10 percent annually. How much will she have accumulated by the fifth year of this investment? 421.82 363.21 287.82 315.91

Watch Calculate the Present Value for Multiple Cash Flows, then answer the following questions:1. Provide a practical example from your own personal financial management of why an understanding of the present value of future cash flows would be important.2. You expect to receive $10,800 one year from now, $17,400 two years from now, nothing at the end of the third year, and $24,000 four years from now. If you discount all your cash flows at 7%, then with annual compounding, what are these future cash amounts worth to you in total today? Check your answers using Excel. Submit both your handwritten calculations and your Excel file.
