Carow Industries has just started to deposit $200 at the end of each month into its employees' retirement fund (i.e., the first deposit will take place one month from now). These deposits will continue for each employee until they retire. Philip Powell, an employee at Carow Industries is planning to retire in 20 years. When he retires, Philip would like to withdraw $5,000 per month (at the end of the month) from his retirement account for the following 25 years. If Philip currently has $50,000 invested and he can earn 3.6% APR, compounded monthly on all money invested, how much will he need to put into the account at the end of each month for the next 20 years in order to have enough money to retire and make the withdrawals as planned?
