Answer:
Emily can deduct the $1,975 in medical expenses from her adjusted gross income.
Step-by-step explanation:
Before an individual could deduct medical expenses as long as they exceeded 7.5% of their adjusted gross income (currently it's 10%).
If Emily's AGI = $43,000, then she will be able to deduct medical expenses that exceed $3,225 (= $43,000 x 7.5%).
Emily's medical expense deductions = $5,200 - $3,225 = $1,975.
If this situation happened this year, Emily would have only been able to deduct $900 [= $5,200 - ($43,000 x 10%)]
