Assume that all interest rates are certain - all investors know how interest rates will change over time. Three years ago, you purchased a 10-year bond with a face value of $1,000.00 and annual coupons of 7.5%. One year after you purchased the bond, the one year spot rate was 5.9% and the two year spot rate was 8.9%. You reinvested the first two coupon payments at the prevailing rates and then sold the bond after three years at a yield to maturity of 10.4%. If your realised compound yield on the bond was 14.8%, what was the bond's initial purchase price? a. $723.62 b. $732.73 c. $721.58 d. $729.73 e. $727.24 f. $722.25 g. $730.75 h. $724.97
