Answer:
C) $2,500
Step-by-step explanation:
First of all, Steve and Leslie's income is less than $400,000, so they can apply for both tax credits.
Steve and Leslie can receive up to $2,000 per year on child tax credit, since Lily is under 17.
They can also claim $500 per year on family tax credit, since Dennis's income is less than $4,150 and he lives with them.
Their total tax credit = $2,000 + $500 = $2,500
