Answer:
c. $1,400
Explanation:
The computation of the amount which is reported in the gross income is shown below:
= Interest on U.S. government bonds + Interest on a Federal income tax refund + Gain on the sale of Madison County school bonds
= $700 + $200 + $500
= $1,400
The Interest on Madison County school bonds $600 is exempt. So, it is not taxable and thus not included in the gross income.
