Bond A pays $8,000 in 20 years. Bond B pays $8,000 in 40 years. (To keep things simple, assume these are zero-coupon bonds, which means the $8,000 is the only payment the bondholder receives.)

Suppose the interest rate is 3.5 percent.

Using the rule of 70, the value of Bond A is approximately ________, and the value of Bond B is approximately _________.

Now suppose the interest rate increases to 7 percent.

Using the rule of 70, the value of Bond A is now approximately ______ , and the value of Bond B is approximately _______

Comparing each bonds value at 3.5 percent versus 7 percent, Bond As value decreases by a _________ percentage than Bond Bs value.

The value of a bond ________ when the interest rate increases, and bonds with a longer time to maturity are sensitive to changes in the interest rate.
