Elena computed 5 percent of her gross income, rounded the resulting figure down to the nearest $100....
10% of $34,500 = $3450
So, 5% of $34,500 = $1725
Rounded DOWN to the nearest $100, $1725 becomes $1700

... and subtracted $50 for each dependent that she claimed.
Elena has 2 dependents
So, we subtract a total of $100

$1700 - $100 = $1600

Answer: A
