Answer:
$250
Explanation:
Currently for the 2019 (due 2020), you can deduct medical expenses that exceed 7.5% of your AGI, but back then in 2014, the threshold was 10%, not 7.5%.
So the Davenports can only deduct $6,750 - ($65,000 x 10%) = $250 if they decided to itemize their deductions.
The threshold will increase back to 10% starting 2020 (due 2021) tax returns.
