Answer:
a. Theresa has $200 interest income and a $400 loss from the bond in 2017
Explanation:
Since the bond was sold for $9,800 which includes the $200 accrued interest that means it reflects the interest income of $200
And, if we exclude the interest income from the sale value of bond, then the value is $9,600 and its purchase price without considering the accrued interest is $10,000. So, after comparing the purchase price and the sale price the loss of $400 would be determined
$9,600 - $10,000 = $(400)
