Use Excel: What is the present value of a cash flow of $150,000 that occurs in 2, or 5, or 7, or 12, or 20, or 30 years (from now) if the discount rate is 20%, or 15%, or 10%, or 5%? (There will be 24 answers in total). In addition to reporting the numerical answers, graph your answers, using a 3-D Column chart with the data table included. The chart should help you visualize how present values are affected by time and changes in interest rates.
