Estimating a Tip



To estimate the amount of a tip round the total bill to the most significant place value. A $16.75 meal would round to $20. Next, move the decimal point of the rounded amount one place to the left. This will be 10% of the total cost. Next divide this amount in half to determine 5%. Add the 10% amount and the 5% amount together to estimate 15% of the total. In this case, it would be a $2.00 + $1.00 = $3.00 tip.

What is the estimated 15% tip?
