You own a bond with the following features: face value of $1000, coupon rate of 6% (semiannual compounding), and 15 years to maturity. The bond has a current price of $1,200. The bond is callable after nine years with the call price of $1100. What is the yield to call if the bond is called at nine years (state as an APR)? Enter your answer as a percentage, without the percentage sign ('\%'). and rounded to 2 decimal places. For example, if your answer is 0.123456, as a percentage this is 12.3456%. so just enter 12.35
