I need help with PART C please. Thank you!

Jenna bought a bond that was issued by Sherlock Watson Industries (SWI) three years ago. The bond has a $1,000 maturity value, a coupon rate equal to 9 percent, and it matures in 17 years. Interest is paid every six months; the next interest payment is scheduled for six months from today.

1. If the yield on similar risk investments is 11 percent, what is the current market value (price) of the bond?
   1. Current Price - $858.79
2. Compute the capital gains yield, current yield, and total yield that Jenna will earn if she holds the bond until it matures. Assume that the market rate does not change from now until maturity.
3. Suppose that Jenna decides she wants to sell the bond seven years from today when 10 years remain until maturity. If the market rate is 8 percent at the time she sells the bond in seven years, for what price will Jenna be able to sell the bond? Compute the capital gains yield, current yield, and total yield that the new investor will earn if he or she holds the bond until it matures 10 years later. Explain why the capital gains yield is negative each year to maturity. Assume that the market rate does not change from the time Jenna sells the bond until it matures.
4. Suppose that Jenna just bought a newly issued 15-year bond with a coupon rate equal to 7 percent. If Jenna sells the bond at the end of the year when its market price is $917, (i) what would be the bonds yield to maturity and (ii) what return would she earn? What portion of the return represents capital gains and what portion represents the current yield? (iii) What return would the new investor earn in the year after James sells the bond? Assume interest is paid semiannually.
5. Suppose that James just bought the same 15-year bond that Jenna bought and at the same time. If James sells his bond five years from the day he purchased it (with 10 years remaining to maturity) for $1,074, (i) what would be the bonds yield to maturity when he sells it and (ii) what return would he earn during the time he held the bond? What portion of the return represents capital gains and what portion represents the current yield? (iii) What return would the new investor earn in the year after James sells the bond? Assume interest is paid semiannually.
