What is the tip for a $21.50 meal if the tip for a $78.00 restaurant bill is $9.20?
Given : Restaurant Bill = $78.0
Tip on the bill is $9.20
We will calculate what percentage of the bill is the tip,
Tip amount x 100 / Bill amount
( 9.20 x 100 / 78.0) = 920 /78 = 11.8 % or 12% so, the tip they paid is 12% of the bill.
if the restaurant bill is 21.50 use, then the amount of the tip will be 12 % of it.
Tip amount is 12% of 21.50 which is;
(21.50 x 12 ) / 100 or $2.58
so the net amount they have to pay is 21.50 + 2.58 = 24.08.
