Answer:
$82.66
Step-by-step explanation:
you purchased a bond for $839.67
coupon = $1,000 x 8% = $80
you sell the bond at the end of the year for $842.33
total dollar return on your investment = coupon + (selling price - purchase price) = $80 + ($842.33 - $839.67) = $82.66
total return in % on your investment = $82.66 / $839.67 = 9.84%
