Current Attempt in Progress

The following two bonds are identical $(\backslash (\backslash$mathrm$\{$FV$\}=\backslash$$ $1,000,8\backslash )-$percent coupon rate paid semi$-$annually$),$ except that they mature at different times:

If the market yield, currently $7$ percent, increases by $100$ basis points, which bond's price will change more and by how much? $($Round present value factor calculations to $5$ decimal places, e$.$g$.1\mathrm{.}25124$ and final answers to $2$ decimal places, e$.$g$.5\mathrm{.}25.)$

Bond C in price by $\backslash$$ or $\backslash \%$

Bond D in price by $\backslash$$ or $\backslash \%$

The price of will change more.
