If you are calculating the exact amount to the penny, I can see it being a bit of a challenge. But why would anybody do that?
Estimating 10% and 20% shouldn't be hard for most people. Then pick a number in between the two, depending on how the service was.
Bill is $78.50
round to $80
ANYONE should be able to tell you that 10% of $80 is $8 and 20% is $16, so tip between $8 and $16.
My 8 year old can easily figure that out.
