Answer/Explanation:
Susan's veterinary expenses are deductible for adjusted gross income
because she is self-employed and at the same time her vet practice constitutes a business.
Therefore, all of her veterinary expenses are deductible for adjusted gross income.
Alexandra is said to be in a trade or business as an employee and
the unreimbursed expenses of an employee are deducted as miscellaneous itemized deductions.
Therefore, Alexandra only benefits if she itemizes her deductions while Susan will always get the full benefit of the deduction.
