Suppose your total taxable income this year is 75000. You are taxed at a rate of 10 percent on the first 25000 20 percent on the next 25000 and 30 percent on the final 25000. What is your total income?

To calculate your total tax, you would apply the rates to each portion of your income. For the first $25,000, you pay 10%, which is $2,500; for the next $25,000, you pay 20%, which is $5,000; and for the final $25,000, you pay 30%, which is $7,500. Adding these amounts together, your total tax is $15,000. Therefore, your total income after tax is $75,000 - $15,000 = $60,000.
