How we worked it out

Updated as you change the numbers.

  1. Tax = $100.00 × 8.25%.

Method and assumptions

Sales tax = price × rate. To remove tax from a total, divide by (1 + rate); subtracting the rate from the total gives the wrong answer. Stores round tax to the cent on each item or on the receipt total, so receipts can differ by a cent.

Questions
