Sylvia's total income does not exceed the standard deduction for a single individual who is not a dependent in 2016, which leads to a taxable income of $0.
The question relates to determining Sylvia's taxable income for 2016 given her earned and interest income, while not being claimed by her parents as a dependent. The total income is the sum of her part-time job earnings ($4,200) and interest income ($2,000), resulting in $6,200. In 2016, the standard deduction for a single individual who is not a dependent was $6,300, which allows Sylvia to deduct this amount from her total income to determine taxable income. Since her income does not exceed the standard deduction, her taxable income is $0.
Sylvia's taxable income for 2016 is $0, as her total income does not exceed the standard deduction for a single individual who is not a dependent.
