Mental math for a $115.00 bill
Ten percent of $115.00 is $11.50: just move the decimal point one place to the left. From there, 20% is double ($23.00), 15% is 10% plus half of 10% ($11.50 + $5.75 = $17.25), and 5% is half of 10% ($5.75).

Before or after tax?
Etiquette guides recommend tipping on the pre-tax subtotal. In practice, many people tip on the total, and the difference is small: at 8% sales tax, a 20% tip on the post-tax amount of a $115.00 pre-tax bill is $24.84 instead of $23.00, about $1.84 more. Check whether a service charge or gratuity has already been added, which is common for parties of six or more; in that case no extra tip is expected.
