Discount off意思

"Discount off" is a term commonly used in the context of sales and promotions to indicate a reduction in the original price of a product or service. It means that the final price you pay for an item will be lower than the listed price due to a discount being applied.

For example, if a product is originally priced at $100 and there is a discount of 20% off, the calculation would be:

Original price: $100 Discount percentage: 20% Discount amount: 20% of $100 = 0.20 * $100 = $20

Final price after discount: $100 - $20 = $80

So, in this case, you would pay $80 for the product instead of $100 because of the 20% discount off the original price.
