You have gathered the following data on three bonds:

Bond	Maturity	Coupon
A	10 yrs	9%
B	9 yrs	1%
C	5 yrs	5%

a. If the market's required return on all three bonds is 6%, what are the market prices of the bonds (you can assume annual interest payments)

b. The market's required return suddenly rises to 7%. What are the new bonds' prices, and what is the percentage change in price for each bond?

c. If the market's required return falls from the initial 6% to 5%, what are the new prices, and what is the percentage change in each price relative to the answer obtained in part (a)?

Please try for shown work.
