Consider three bonds with 6.70% coupon rates, all making annual coupon payments and all selling at face value. The short-term bond has a maturity of 4 years, the intermediate-term bond has a maturity of 8 years, and the long-term bond has a maturity of 30 years.

a. What will be the price of the 4-year bond if its yield increases to 7.70%? (Do not round intermediate calculations. Round your answers to 2 decimal places.)

b. What will be the price of the 8-year bond if its yield increases to 7.70%? (Do not round intermediate calculations. Round your answers to 2 decimal places.)

c. What will be the price of the 30-year bond if its yield increases to 7.70%? (Do not round intermediate calculations. Round your answers to 2 decimal places.)

d. What will be the price of the 4-year bond if its yield decreases to 5.70%? (Do not round intermediate calculations. Round your answers to 2 decimal places.)

e. What will be the price of the 8-year bond if its yield decreases to 5.70%? (Do not round intermediate calculations. Round your answers to 2 decimal places.)

f. What will be the price of the 30-year bond if its yield decreases to 5.70%? (Do not round intermediate calculations. Round your answers to 2 decimal places.)
