# Calculations with Percents

## Taxes, Tips, and Mark Ups

All of the things above are calculated by finding the percent of the number and then adding it to the original number.

## Taxes

My example of tax is starts at a car dealer. The car costs 24,999 with a 7.00% tax, which is \$1749.93. So the car with tax costs \$26748.93.

## Tips

I went to Applebee's where my meal costs \$25.67 before tip. I decided to give a 20% tip so the tip is \$5.13. The total with tip is \$30.80.

## Mark Ups

My example of Mark up is a shoe store gets a new pair of shoes for \$130 but they sell them for \$160. So they marked them up \$30. They marked it up 23.1%

## Discounts

Discounts are calculated by finding a percent of a number and then subtracting it from the original price.

## Discounts

My example for discounts are I have a coupon 10% off of a \$10.00 purchase. 10% of \$10 is \$1 so I got a discount of \$1.

## Commission

A percent of a number

## Example

A car salesman get a percent of how much the car costs. He gets 10% of a car that costs \$10,000 so he gets \$1,000 of commission.
