If you tip someone such as a waiter in a restaurant, you give them some money in order to thank them for their services.

Being able to accurately tip can save you both time and money and can ensure that the person providing the service to you is adequately compensated.

**Formula to calculate tip.**

- Find the total of your pretax bill.
- Move the decimal point to the left one place.
- Round up.
- Double the number

**Example:**

Suppose your pretax bill was $ 70.0. Calculate your tip.

Since we know your total pretax bill so we’ll begin by moving the decimal to the left to get **$ 7.00.**

Since we get a whole there is no need to round up.

Then we double it.

**= 7.00 x 2**

**= 14.00**

Therefore, your tip will be worth $ 14.00.
