Michael won the Powerball jackpot of 57 million dollars. He has two options to collect the cash: (a) 30-year annuities (first payment one year from today) which future value equates the jackpot amount given that the prevailing interest rate is 8% per year; (b) a single payment now, corresponding to the present value of those 30-year annuities. Michael has big plans, hence he prefers option (b). Assuming that there are no taxes, how much money will he be able to collect now
