Answer: 
Your monthly payment is $26.72.
Example: Saving With Monthly Deposits
Note: Accounts with payments made at the beginning of the period are 
referred to as annuity due accounts. Interest begins accumulating earlier 
and produces slightly higher yields.
You invest $200 at the beginning of each month in a retirement plan. 
What will the account balance be at the end of 20 years, if the fund earns 
an annual interest of 7.5 % compounded monthly, assuming beginning-
of-period payments?
