5. Burt is saving up for his retirement. Today is his 36th birthday. Burt first started saving when he was 25 years old. On his 25th birthday, Burt made the first contribution to his retirement account when he deposited $1,500. Each year on his birthday, Burt has ontributed another $1,500 to the account. The 12th (and last) of these contributions was made earlier today on his 36th birthday. The account has paid an effective annual rate of return of 6.4%. a) How much will Burt have in the account on his 36th birthday (after the contribution mentioned above)? Burt wants to close the account tomorrow and move the money to a stock fund which is expected to earn an effective annual return of 8.3% a year. Burt's plan is to continue making contributions of an undetermined amount to this account each year on his birthday. His next contribution will be one year from today (age 37) and his final planned contribution will be on his 66th birthday (30 additional contributions in all). Burt hopes to withdraw $8,000 a month for 20 years after he retires (240 withdrawals starting one month after his 66th birthday). b) How much does Burt need in his account on his 66th birthday to fund the future withdrawals? c) How much does each of the 30 annual contributions (from age 37 to 66) need to be to reach this goal?
