How Discount Calculations Work

Discounts are calculated by finding a percentage of the original price and subtracting that amount from the original price. The formula used is:

Discount Amount = Original Price × (Discount Percentage ÷ 100)

Final Price = Original Price - Discount Amount

For example, if you have an original price of $15 and a discount of 30%, the calculation would be:

Discount Amount = $15 × (30 ÷ 100) = $4.50

Final Price = $15 - $4.50 = $10.50

This means you save $4.50, and the final price you pay is $10.50.
