How the tip is calculated

If "Calculate tip on pre-tax amount" is unchecked, the tip is calculated on the bill amount as entered. If checked, the tip is calculated on the bill before sales tax is added — useful if the bill total already includes tax. The total is then split evenly across the number of people.
