$1.$ A $15-$ear $7\%$ coupon $($semiannual$)$ bond sells for $$1030,$ what is the bond holder$$s YTM$?$

$2.$ On the issue date, you bought a $15-$year maturity, $6\mathrm{.}55\%$ semi$-$annual coupon bond. The bond then sold at YTM of $6\mathrm{.}15\%.$ Now, $7$ years later, the similar bond sells at YTM of $5\mathrm{.}75\%.$ If you hold the bond now, what is your realized rate of return for the $7-$year holding period?
