Last year, Joan purchased a $1,000 face value corporate bond with an 11% annual coupon rate and a 10-year maturity. At the time of the purchase, it had an expected yield to maturity of 12.45%. If Joan sold the bond today for $989.57, what rate of return would she have earned for the past year? Round your answer to two decimal places.

An investor has two bonds in her portfolio, Bond C and Bond Z. Each bond matures in 4 years, has a face value of $1,000, and has a yield to maturity of 8.5%. Bond C pays a 11.5% annual coupon, while Bond Z is a zero coupon bond.Assuming that the yield to maturity of each bond remains at 8.5% over the next 4 years, calculate the price of the bonds at each of the following years to maturity.(Year 0 to Year 4) Round your answer to the nearest cent.
