Answer:
6.64%
Explanation:
yield to maturity (YTM) = {preferred dividend + [(faced value - market value)/n]} / [(face value + market value)/2]
yield to maturity (YTM) = {$1.10 + [($75 - $68)/80]} / [($75 + $68)/2]
yield to maturity (YTM) = $1.1875 / $71.50 = 0.0166 quarterly yield x 4 = 0.0664 = 6.64% annual yield
