The YTM on a 6-month $50 par value zero-coupon bond is 17.3%, and the YTM on a 1-year $100 par value zero-coupon bond is 19.7%. Furthermore, the YTM on a 1.5-year $100 par value zero-coupon bond is 21.6%, and the YTM on a 2-year $100 par value zero-coupon bond is 23.9%. These YTMs are semiannual BEYs. What would be the arbitrage-free price of a 2-year bond with the coupon rate of 20% (semiannual payments) and par value of $10,000? Assume that this bond is issued by the same company as the zero-coupon bonds. Round your answer to 2 decimal places. For example, if your answer is 25.689, please write down 25.69.
