Answer:
$100
Step-by-step explanation:
Since the standard deduction for 2017 was $6,350, and Graciela only reported $100 more, she needs to report only $100 of the state tax refund. State tax refunds are not considered income unless you itemize your deductions, and in case you did, like Graciela, you must only report the amount that exceeds the standard deduction.
