(A) Having graduated and secured jobs, you and your spouse begin saving for retirement. At this point, your retirement fund has a balance of $0. You begin depositing $300 each month, starting one month from now, for the next 30 years. Your spouse begins depositing $5,000 each year, starting one year from now, into the same account for the next 30 years. The joint account earns 9 percent APR, compounded monthly. How much will you two have in your joint account 30 years from now, immediately after your last deposits?

(B) Your retirement fund is expected to be funded by monthly withdrawals, starting one month after your last deposits, and it is expected to last for 35 years. How much will you two (collectively) have to spend each month, assuming your accounts continue to earn the same rate as before?
