Details in formula and caculation please so that I can understand. Thankyou.

Part C

(1) What is the yield to maturity on a 10-year, 11.5% annual coupon, $1,000 par value bond that sells for $887.00 (a)? That sells for $1,134.20 (b)?

(2) What are the total return, the current yield, and the capital gains yield for the discount bond? Assume that it is held to maturity and the company does not default on it.

Part D

How does the equation for valuing a bond change if semiannual payments are made? Find the value of a 10-year, semiannual payment, 10% coupon bond if nominal rd = 15.5%.

Part E

Suppose for $1,000 you could buy a 12.5%, 10-year, annual payment bond or a 12.5%, 10- year, semiannual payment bond. They are equally risky. Which would you prefer? If $1,000 is the proper price for the semiannual bond, what is the equilibrium price for the annual payment bond?
