Answer:

D. $56

Step-by-step explanation:

Sandra's taxable income is $39,250.

That amount works for range 2 ($39,250 - $39,300), so her tax is $5,944.

Sandra paid $6,000 in FWT (federal withholding tax), which is greater than $5,944, so we need the refund here.

Subtract 5,944 from 6,000 to get the refund.

6,000 - 5,944

We can go on ahead and just make this 100 - 44 (5,900 - 5,900 = 0).

100 - 44

Her refund is $56.
