Mental math for a $80.00 bill
Ten percent of $80.00 is $8.00: just move the decimal point one place to the left. From there, 20% is double ($16.00), 15% is 10% plus half of 10% ($8.00 + $4.00 = $12.00), and 5% is half of 10% ($4.00). Round to the nearest dollar if that is easier; a tip of $16.00 instead of $16.00 is well within the normal range.
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 $80.00 pre-tax bill is $17.28 instead of $16.00, about $1.28 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.
