I think of plan saving money for do not work any more on over the following 25 years. For doing so, we want to invest $850 monthly in a stocks account and $450 per month in a bonds account. The profit of the stocks account remains expected to have an APR of 10.5 %, and the bonds account to earn an APR of 6.5 %. Once we retire, we will associate our money in the account with APR of 7.5 %. Every interest rate remains compounded in month.

How much you will Withdrawal$___________ per month period of 20 years?
