Discount on Total Bill : Example Percentage Calculation

Your restaurant bill is $80, and there's a 15% service charge added to it. You want to leave a 20% tip on the total bill. How much should the tip be?

Solution:

• Calculate the service charge: 15% of $80 = $12.
• Add the service charge to the total bill: $80 + $12 = $92.
• Calculate the tip: 20% of $92 = $18.40.

The tip should be $18.40.
