# Percentages in the Real World

## Taxes

Tax is extra money added on to a bill to pay to the city, state, or federal treasury.

## Tips

Tips are money you give to waiters/waitress's for services at restaurants.

## Mark-ups

Mark-ups is when you buy something at its own price, then sell it for a bigger price

## Discount

Discounts is when you get a small price off a bill, usually with coupons or sales.

## Commission

Commission is where people who try to sell stuff get a part of a sale.

## Taxes example

I go to the Exchange and get a game for \$40.00 with 2% tax. You divide 40.00 by 100 and multiply the result by 2, getting \$0.80. You then add the 80 cents to the 40 dollars and you get a total of \$40.80.

## Tips example

I eat at IHOP and receive \$16.43 on my bill, and I leave the waiter a 17% tip. I multiply .17 and 16.43 and get 2.7931 for an answer. I round my answer to the nearest hundreds an get 2.79. The waiter's tip is \$2.79.

## Mark-up example

I am trying to start a business selling toys I buy 20 for \$10 each and sell them for \$20 each. I divide 10 by 100 and get 0.1. Then I divide 20 by .1 and get 200. Thus I get twice the amount I payed for.

## Discount example

GameStop is having a sale: 40% off all PC games. I want Civ Beyond Earth. It costs \$60.00, so I take the discount off of 60 dollars. I multiply 0.01 and 60 and get .6 then I multiply .6 and 40 and I get 24. I take off the \$24, so then I only have to pay \$36

## Commission example

I sold 4 cars as a car salesman. I get 10% of the money from each car, and each car costs \$23,000. 23,000x0.01 = 230 ---> 230x10 = 2,300- money made from one car 2,300x4 =9,200 So, I earned \$9,200 from selling the 4 cars
