Answer:
$800
Step-by-step explanation:
The amount of student loan interest can Zach and his spouse deduct in 2018:
Education expenses:
= Incurred expenses - Scholarship
= $10,000 - $2,000
= $8,000
⇒
![(8,000)/(10,000)*100](https://img.qammunity.org/2020/formulas/business/college/t21b5p51o5bkbk1fhqi542wu7edexvd8dc.png)
= 80%
Interest incurred:
= Federal loan interest + Lending loan interest
= $700 + $300
= $1,000
Therefore, the amount of student loan interest can Zach and his spouse deduct in 2018 is = Interest incurred × Education expenses percent
= $1,000 × 80%
= $800
