i only need the approximate yeild to maturity. i got 15 % and that is not right.

Check my work Bond x pays $85 annual interest and has a market value of $780. It has 12 years to maturity Bond Z pays $95 annual interest and has a market value of $800. It has five years to maturity Assume the por value of the bonds is $1.000 Compute the current yield on both bonds. (Do not round Intermediate calculations. Input your answers as a percent rounded to 2 decimal places.) Band X Bond 2 Current Yield 10.30 11.88 b. Which bond should he select based on your wees to portal Band Z Bondx c. Adrwock of current yield is that it does not consider the total life of the bond For example, the normale yeld to maturity on Bond is 1190 percent. What is the approximate is to maturity on Bond Z? The exact yold to maturity (Use the approximation formin to compute the approximate yled to maturity and use a calculator or Excel to compute the exact yield to maturity. Do not Yound Intermediate calculations. Input your newers as a percent rounded to 2 decimal places) Bond z O Bond X c. A drawback of current yield is that it does not consider the total life of the bond. For example, the approximate yield to maturity on Bond X is 11,90 percent. What is the approximate yield to maturity on Bond Z? The exact yield to maturity? (Use the approximation formula to compute the approximate yield to maturity and use a calculator or Excel to compute the exact yield to maturity. Do not round Intermediate calculations. Input your answers as a percent rounded to 2 decimal places.) Approximate yield to maturity Exact yield to maturity % 15.54% d. Has your answer changed between parts band cof this question? Yes
