To calculate a 10% tip, you can follow these steps:
Determine the bill amount: Look at your restaurant bill and find the total amount due.
Calculate the tip amount: Multiply the bill amount by 0.10 (which is the decimal equivalent of 10%). For example, if the bill amount is $50, you would calculate 0.10 x $50 = $5.
Add the tip amount to the bill amount: Add the tip amount you calculated in step 2 to the original bill amount to find the total amount due, which includes the tip. For example, if your bill was $50 and you left a $5 tip, the total amount due would be $55.
So, if you want to leave a 10% tip, you simply multiply the bill amount by 0.10 to get the tip amount and add it to the original bill amount to get the total amount due.
