Bryson DeChambeau bought $$1000$ par value, $20-$year bonds issued by Pinnacle Inc. $7$ years ago for $$1,056\mathrm{.}49.$ The bonds make semiannual coupon payments at a rate of $5\mathrm{.}5$ percent. If the current price of the bond is $$973\mathrm{.}28,$ what is the yield that Bryson would earn by selling the bonds today? $($Hint: Think of how long the bond was held. Do not round intermediate calculations and round your answer to $2$ decimal places, e$.$g$.,32\mathrm{.}16.$ Do not input a percent sign with your final answer.$)$
