Answer:
$300
Step-by-step explanation:
According to the Internal Revenue Service (IRS), interest on a state or local government obligation may be tax-exempt even if the obligation is not a bond.
Therefore the interest received that will be included in gross income will exclude interest income from the following investments: $400 from State of Wyoming bonds and $50 from City of Laramie bonds.
$100 from U.S. Treasury bonds are taxable at federal level, hence will be included.
Therefore taxable amount = $100 from treasury bonds and $200 from Ford Motor Co.
