Congratulations! You have just used your knowledge of decimals, proportion and percent in a real-life situation. Discounts and tax are all around you everyday and it is important that you know how to correctly calculate what an item costs if it is on sale.
Remember: 1. To find a percent of a number, convert the percent to a decimal (move the decimal left two places) and multiply by the number. 2. Discount is a percent of the original price of an item. 3. Discount is subtracted from the original price of an item. 4. Tax is a percent of the sale price of an item. 5. Tax is added to the sale price of an item. 6. Shipping and handling are also added to the cost of an item.
