Finance question

[Please-Help1]

Good Corporation, Inc. (GPI) sold $1,000,000 of 12 percent, 30-year, semiannual payment bonds 15 years ago. The bonds have a sinking fund provision which requires GPI to redeem 5 percent of the original face value of the issue each year ($50,000), beginning in Year 11. To date, 25 percent of the issue has been retired. The company can either call bonds at par for sinking fund purposes or purchase bonds on the open market, spending sufficient money to redeem 5 percent of the original face value each year. If the yield to maturity (15 years remaining) on the bonds is currently 14 percent, calculate the amount of money GPI must put up to satisfy the sinking fund provision for this year.
