Percent Applications

Lesson 7.6

OBJ: To find markups, discounts, sales tax, and tips

- An increase from the wholesale price of an item to the retail price.
- Retail Price = wholesale + markup
- Retail = wholesale x (100% + Markup percent)
- Example – What is the retail price of a bracelet that has a wholesale cost of $7 if the markup percent is 120%?

- A decrease from the original price of an item to the sale price.
- Sale Price = Original price – Discount
- Sale Price = Original Price x (100% - Discount Percent)
- Example - A pair of jeans that originally costs $42 is 25% off. Find the sale price.

- Sales Tax – A tax based on the amount paid for goods bought, usually added to the price. It is calculated using percents.
- Tip – An amount of money given based on the percentage of bill and service. It is calculated using percents.
- Example – The bill for your restaurant meal is $23. You leave a 15% tip. The sales tax is 5%. What is the total cost of the meal?
- ** The tip is based on the food bill only. Do not include the sales tax when finding a tip.

- Retail Price = Whole Price x (100% + Markup percent)
- Example – A store marks up the wholesale price of a printer by 80%. The retail price is $120. What is the wholesale price of the printer?

- Find the retail price of a collectible figurine with a wholesale cost of $12 that is marked up 75%.
- Mason buys a suit that is on sale for 20% off the original price of $180. What is the sale price?

- The bill for a family’s meal at a restaurant is $68. They leave a 15% tip. The sales tax is 6%. What is the total cost of their meal?
- A dress shop marks up the wholesale price of a prim dress by 115%. The retail price is $180. What is the wholesale price of the dress?
