Markup 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%?

Discounts 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.

**Using Sales Tax and Tips**

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.
