Final answer:
Using the given state income tax rate of 3.5%, Hussein's state income tax for the year on a federal taxable income of $31,500 would be $1,102.50.
Step-by-step explanation:
Hussein has a federal taxable income of $31,500. To calculate his state income tax, which is 3.5% of his federal taxable income, we use the formula: state income tax = taxable income × state tax rate. Therefore, Hussein's state income tax would be calculated as follows:
State income tax = $31,500 × 3.5% = $31,500 × 0.035 = $1,102.50.
Thus, Hussein's state income tax for that year would be $1,102.50.
