(Bond valuation) You are examining three bonds with a par value of $1,000 (you receive $1,000 at maturity) and are concerned with what would happen to their market value if interest rates (or the market discount rate) changed. The three bonds are Bond A - a bond with 3 years left to maturity that has a 6 percent annual coupon interest rate, but the interest is paid semiannually. Bond Ba bond with 7 years left to maturity that has a 6 percent annual coupon interest rate, but the interest is paid semiannually. Bond Ca bond with 20 years left to maturity that has a 6 percent annual coupon interest rate, but the interest is paid semiannually. What would be the value of these bonds if the market discount rate were a. 6 percent per year compounded semiannually? b. 3 percent per year compounded semiannually? c. 9 percent per year compounded semiannually? d. What observations can you make about these results
