You purchased a zero coupon bond one year ago for $275.83. The market interest rate is now 9 percent. If the bond had 15 years to maturity when you originally purchased it, what was your total return for the past year? I did 1000/(1.09^14) = 299.25 (299.25-275.83) / 275.83 = 8.49% However the answer in the back of the book says that it is 5.71% That means that the face value is $868.11 not $1000, but how do I get the $868.11 as the face value? Please help, Thank you
