you are planning to save for retirement over the next 35 years. to do this, you will invest $770 per month in a stock account and $370 per month in a bond account. the return of the stock account is expected to be 9.7 percent, and the bond account will return 5.7 percent. when you retire, you will combine your money into an account with a return of 6.7 percent. how much can you withdraw each month from your account assuming a 30-year withdrawal period? (do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
