Jacob just used $$97\mathrm{.}51$ purchased a Treasury bond. Assume that the yield rate for this bond is j$2=3\mathrm{.}44\%$ p$.$a$.$ and the duration of this bond is $3\mathrm{.}79$ years. Without actually calculating the new price for this bond, use the bond price and the duration value to estimate $($use the price sensitivity formula$)$ the change in price of this bond that would result from an increase in yield rate $($j$2)$ of $18$ basis points. Round your answer to four decimal places.

a$.$

$-0\mathrm{.}6431$

b$.$

$-0\mathrm{.}3270$

c$.$

$-0\mathrm{.}3215$

d$.$

$-0\mathrm{.}6540$
