Calculating Sales Tax and Discounts

I can calculate the final price of an item after sales tax or a discount.

• 1

  To calculate sales tax, convert the sales tax percentage into a decimal and multiply it by the price of the item.

• 2

  To find the final price, add the sales tax amount to the original price of the item.

• 3

  Another method to find the final price is to multiply the original price by 1 plus the sales tax rate in decimal form, such as 1.06 for a 6% tax.
