Consider a bond selling at par with a coupon rate of $6\%$ and $10$ years to

maturity. The issuer makes semi$-$annual coupon payments. What is the price

of this bond if the required yield is $15\%?$ What if the yield is $16\%?$

$$563\mathrm{.}34$ for $15\%,$ and $$591\mathrm{.}87$ for $16\%$

$$541\mathrm{.}25$ for $15\%,$ and $$509\mathrm{.}09$ for $16\%$

$$509\mathrm{.}09$ for $15\%,$ and $$541\mathrm{.}25$ for $16\%$

$$525\mathrm{.}41$ for $15\%,$ and $$590\mathrm{.}90$ for $16\%$
