Step-by-step explanation:
The total amount of other dependent credit that Skylar and Walter Black can claim is $1,000.
They claim a $500 other dependent credit for each of their dependents, Rebecca Backin and Alton Black. Since they have two dependents, they can claim a total of $500 + $500 = $1,000.
