financial real estate question :)

Two 30-year maturity mortgage-backed bonds are issued. The first bond has a par value of $10,000 and promises to pay a 7.5 percent annual coupon, while the second is a zero coupon bond that promises to pay $10.000 (par) after 30 years, with interest accruing at 7.0 percent. At issue, bond market investors require a 9.0 percent interest rate on both bonds. Required: a. What is the initial price on each bond? b. Now assume that both bonds promise interest at 7.5 percent, compounded semiannually. What will be the initial price for eoch bond? c. If market interest rates fall to 6.5 percent at the end of the fifth year, what will be the value of each bond, assuming annual payments as in (a) (state both as a percentage of par value and actual doliar value)? What is the initial price on each bond? (Do not round intermediate calculations. Round your final answers to 2 decimal places.) Now assume that both bonds promise interest at 7.5 percent, compounded semiannually. What will be the initial price for each bond? (Do not round intermediate calculations. Round your final answers to 2 decimal places.) If market interest rates fall to 6.5 percent at the end of the fifth year, what will be the value of each bond, assuming annual payments as in (a) (state both as a percentage of par value and actual dollar value)? (Do not round intermediate calculations. Round your final answers to 2 decimal places.)
