4. Now assume that your wealthy grandfather wants to invest some money in your behalf. He wants the money to be worth $65,000 on December 31, 2025. How much money will he need to invest on a one-time basis on December 31, 2020 in order to earn enough interest to accumulate to $65,000 by December 31, 2025? Assume a 5% interest rate. (Hint: I recommend that you use the PV formula in Excel to solve this problem.) Use the information from Question 4 except assume that the interest rate is 3% per year. How much will he have to invest on a one-time basis on December 31, 2020 to have $65,000 by December 31, 2025? Please use excel and show the formula and screenshot
