Final answer:
Option (e), Riley can deduct $2,475 for qualifying education interest based on their modified AGI of $71,000.
Step-by-step explanation:
To determine the deduction for qualifying education interest, we need to look at the IRS guidelines. For single filers like Riley, the maximum deduction for qualifying education interest is $2,500. However, the eligibility for the deduction is based on the modified adjusted gross income (MAGI).
In Riley's case, with a modified AGI of $71,000, the deduction begins to phase out once the MAGI exceeds $70,000. The phase-out is gradual, with the deduction reduced by 1% for every $2,000 that the MAGI exceeds the threshold.
Since Riley's MAGI is $1,000 above the threshold, the deduction is reduced by 1% of the maximum $2,500 deduction, which amounts to $25. Therefore, Riley can deduct $2,500 - $25 = $2,475 for qualifying education interest.
