Final answer:
Faye's medical expense deduction is $13,350.
Step-by-step explanation:
Faye's medical expense deduction is calculated based on her adjusted gross income (AGI). The deduction is subject to a threshold of 7.5% of her AGI. In this case, Faye's AGI is $120,000.
Therefore, 7.5% of $120,000 is $9,000. Since Faye's total medical expenses of $22,350 exceeds the threshold, she can deduct the amount that exceeds the threshold, which is $22,350 - $9,000 = $13,350.
