### David DeLisi

## Tax example

My bill at McDonalds was $10.00 for a meal. I had to pay 6.75% tax. Therefore it would be $10.68.

## Tip example

When I went to Bob Evans I had a $60.00. bill. I had to pay a tip of 12%. Therefore, I had to give a $7.20 tip.

## Discount example

I wanted a coat at Khols. The original price was $50.00 and today there was a sale, so the price dropped from a 20% discount. So I had to pay $10.00.

## Commission example

I listed my car for $5 ,000. Somebody bought it for 20% of the price. Therefore he bought it for $1,000

## Markup example

The original price of the apples was $5.00. They marked it up by 3% Therefore the price is now $5.15
