Breaking Down the Basics

Before diving into specific scenarios, let's cover the fundamental formula:

Percentage = (Part / Whole) x 100

In the context of prices, the "Part" is often the discount amount or the sales tax, and the "Whole" is the original price.

Calculating Discounts

One of the most common reasons to find the percentage of a price is to determine the discount amount. Here's how to do it:

  1. Identify the Original Price: This is the price of the item before any discount is applied.
  2. Determine the Discount Percentage: This is the percentage by which the price is reduced (e.g., 20% off).
  3. Apply the Formula: Multiply the original price by the discount percentage, then divide by 100.

Example: A jacket costs $80, and there's a 25% discount. The discount amount is (80 x 25) / 100 = $20. The final price is $80 - $20 = $60.

Figuring Out Sales Tax

Sales tax is an additional cost added to the price of goods and services. Here's how to calculate it:

  1. Identify the Original Price: This is the price of the item before tax.
  2. Determine the Sales Tax Rate: This is the sales tax percentage set by the state or local government (e.g., 7%).
  3. Apply the Formula: Multiply the original price by the sales tax rate, then divide by 100.

Example: An item costs $50, and the sales tax rate is 6%. The sales tax amount is (50 x 6) / 100 = $3. The total cost is $50 + $3 = $53.

Finding Percentage Change

Sometimes, you might want to know the percentage change between two prices. For instance, if the price of a product increased from one year to the next.

  1. Identify the Initial Price and the New Price.
  2. Calculate the Difference: Subtract the initial price from the new price.
  3. Apply the Formula: Divide the difference by the initial price, then multiply by 100.

Example: The price of a service was $80 and now it is $100. Percentage Increase: ((100-80)/80)*100 = 25%. The price has increased by 25%
