Here's a trick for computing a 15% tip in your head. Start by calculating 10% of the bill and then add half. For example, if the bill is $24 dollars, a 15% tip would be $2.40 (10%) plus $1.20 (half of 15%), for a total of $3.60.
Another easy method is to use the sales tax rate in your state. If it the tax rate happens to be around %7 or 8%, the tip should be roughly double the amount of tax that is charged.
My tip calculation trick is to just double the first number. This seems to work out in most cases. For the example of $24.00, I would tip $4.00 which would be 16.66%. At the high end, a 29.00 bill would be 13.79%, still pretty close.
hi, i was wondering where to get one of those tip cards. thank you. della
I've done the same thing, make the bill 10% and add half. Goes for shopping sales too. Sometimes my friends can't figure out how I do it, sometimes I can't figure out how they can't! :-)
I would like to get one of those tip cards too. Would anyone know where to find one?
