You invest $$20,000$ into a $10-$year investment that will provide you a return of $6\%$ APR compounded monthly. You agree that you would accept a little less each month if you received the payments at the beginning of each month instead of the end of the month because you would have the money to invest for the entire month. What amount will you receive each month if you receive your payments as an ordinary annuity and as an annuity due, respectively $($remember: PMTDUE $=$ PMTORD $/(1+$ r$))?$
