Michael has a taxable income of $⁢90,000 and his total tax owed is $⁢13,500 What is his effective tax rate?

The effective tax rate is the total tax owed divided by taxable income, then multiplied by 100. Here, $13,500 ÷ $90,000 = 0.15, and 0.15 × 100 = 15 percent. So the correct choice is 15 percent.
