a. A $1,000 bond has a 7.5 percent coupon and matures after ten years. If current interest rates are 10 percent, what should be the price of the bond? b. If after six years interest rates are still 10 percent, what should be the price of the bond?

c. Even though interest rates did not change in a and b, why did the price of the bond change?

d. Change the interest rate in a and b to 6 percent and rework your answers. Even though the interest rate is 6 percent in both calculations, why are the bond prices different?
