Having worked for several years, Suzanne is now planning to save for retirement over the next 30 years. To achieve this goal, she will invest $800 a month in a stock account and $300 a month in a bond account. The expected return on the stock account is 15 percent, and the bond account will pay 6 percent. When retiring, Suzanne will combine her money into a single account with a 5 percent return. How much can she withdraw each month from her account assuming a 20-year withdrawal period?
