Consider three bonds with $6\mathrm{.}40\%$ coupon rates, all selling at face value and making annual coupon payments. 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.

What will be the price of the $4-$year bond if its yield increases to $7\mathrm{.}40\%?$

Note: Do not round intermediate calculations. Round your answer to $2$ decimal places.

What will be the price of the $8-$year bond if its yield increases to $7\mathrm{.}40\%?$

Note: Do not round intermediate calculations. Round your answer to $2$ decimal places.

What will be the price of the $30-$year bond if its yield increases to $7\mathrm{.}40\%?$

Note: Do not round intermediate calculations. Round your answer to $2$ decimal places.

What will be the price of the $4-$year bond if its yield decreases to $5\mathrm{.}40\%?$

Note: Do not round intermediate calculations. Round your answer to $2$ decimal places.

What will be the price of the $8-$year bond if its yield decreases to $5\mathrm{.}40\%?$

Note: Do not round intermediate calculations. Round your answer to $2$ decimal places.

What will be the price of the $30-$year bond if its yield decreases to $5\mathrm{.}40\%?$

Note: Do not round intermediate calculations. Round your answer to $2$ decimal places.

Comparing your answers to parts $($a$),($b$),$ and $($c$),$ are long$-$term bonds more or less affected than short$-$term bonds by a rise in interest rates?

Comparing your answers to parts $($d$),($e$),$ and $($f$),$ are long$-$term bonds more or less affected than short$-$term bonds by a decline in interest rates?
