Ten years to maturity and the required rate of return goes from 6% to 5%. d. Twenty years to maturity and the required rate of return goes from 6% to 5%. e. Compare and contrast your answers for parts a through d and comment on your observations. a. The price of the 6%-coupon bond with 10 years to maturity and 6% required rate of return is $ (Round to the nearest cent.) The price of the 6%-coupon bond with 10 years to maturity and 7% required rate of return is $ (Round to the nearest cent.) If the required rate of return goes from 6% to 7%, the percentage change in the price of the 6%-coupon bond with 10 years to maturity is \%. (Round to two decimal places.) The price of the zero-coupon bond with 10 years to maturity and 6% required rate of return is $. (Round to the nearest cent.) The price of the zero-coupon bond with 10 years to maturity and 7% required rate of return is $. (Round to the nearest cent.) If the required rate of return goes from 6% to 7%, the percentage change in the price of the zero-coupon bond with 10 years to maturity is \%. (Round to two decimal places.) b. The price of the 6%-coupon bond with 20 years to maturity and 6% required rate of return is $ (Round to the nearest cent.) The price of the 6%-coupon bond with 20 years to maturity and 7% required rate of return is $ (Round to the nearest cent.) If the required rate of return goes from 6% to 7%, the percentage change in the price of the 6%-coupon bond with 20 years to maturity is %. (Round to two decimal places.) The price of the zero-coupon bond with 20 years to maturity and 6% required rate of return is $. (Round to the nearest cent.) The price of the zero-coupon bond with 20 years to maturity and 7% required rate of return is $. (Round to the nearest cent.) If the required rate of return goes from 6% to 7%, the percentage change in the price of the zero-coupon bond with 20 years to maturity is %. (Round to two decimal places.) c. The price of the 6%-coupon bond with 10 years to maturity and 5% required rate of return is $ (Round to the nearest cent.)

If the required rate of return goes from 6% to 5%, the percentage change in the price of the 6\%-coupon bond with 20 years to maturity is \%. (Round to two decimal places.) The price of the zero-coupon bond with 20 years to maturity and 5% required rate of return is $. (Round to the nearest cent.) If the required rate of return goes from 6% to 5%, the percentage change in the price of the zero-coupon bond with 20 years to maturity is \%. (Round to two decimal places.) e. Compare and contrast your answers for parts a through d and comment on your observations. (1) The bond's price is more sensitive to interest rate risk because it has a coupon rate. (Select from the drop-down menus.) (2) Regardless of the level of interest rate risk for given bond, the magnitude of the price change that results from an increase in underlying interest rates is than the price change that results from a decrease in interest rates.
