If you have a calculator, multiply the bill amount by 0.15
If not:
Take the amount of the bill.
Move the decimal place one place to the left - that is 10%
Halve that number - that is 5%
Add the two together - and you've got 15%
Simplicity!
So, bill of 37.56
Step 1: 3.76
Step 2: 1.88
Step 3: 5.64
$3.53
The tip would be 8.88 Divide the bill by 10 - giving 5.92. Divide that figure by 2 - giving 2.96 (this is 5% !) Add the two figures together, and the result is 15% of the bill.

38.40 x .15 = 5.76 so the total cost of the meal with tip is $44.16
Booo yeah
quick way to estimate a 10 percent tip is to remove the ones digit.Example: to give 10% tip for 50 = 510% tip for 500 = 50
15 percent tip for 66.60 = 9.9915% of 66.60= 0.15 * 66.60= 9.99
10% of the bill would be 4.10 Half of 10 is 5, so 5% of the bill is 2.05 Estimate $6 for the tip
If the total of your bill is $249.10 and you want to leave a 15 percent tip it would be $37.37.
-- Remember that "15 percent" means 0.15 . -- Multiply the bill by that number to calculate the tip.
