85 * .2 = 17
It is 15% of 24 = 24*15/100 = 3.60 dollars.
Ten percent of 14.41 would be 1.44; double that to get 2.88. For a tip, I'd leave $3 in cash.

A standard tip is usually about 15 percent, so 30 would be about right.
85 * .2 = 17
If the total of your bill is $249.10 and you want to leave a 15 percent tip it would be $37.37.
the TIP will be about $2.17
£6.10
Three dollars and eighty six cents.
The tip would be 4.57. That's the math answer, but if you were there in person, you would probably just leave $5.
