5. Paul McCarthey has been very responsible about retirement. He started saving $10,000 at the end of every year since his famous hit song Cant Buy My Love in 1964. Paul plans to retire at the end of 2024, exactly 60 years after he started saving. He can earn 8% annual interest compounded semi-annually on his investments. a. How much will Paul have in his retirement fund at the end of 2024? b. If Paul would have been content with $25,000,000, how much would he have had to save every year over the 60-year period? c. Given his $10,000 annual deposits, if Paul decides to retire as soon as he raises $25,000,000 how long will he have to invest for? (Hint, remember to adjust your time periods for semi-annual compounding. Also, remember to include Pauls deposits as a negative number).
