Answer:

18%

Step-by-step explanation:

From adjusted gross income of $100,000, subtract the standard deduction of $6,350 and a single personal exemption of $4,050. That makes taxable income equal to $89,600. That amount is just below the upper end of the 25% tax bracket, with the tax calculation amounting to $18,138.75. That works out to an effective tax rate of 18%.
