Calculating discounts is a fundamental aspect of retail and consumer transactions. When an item is offered at a discounted price, understanding the original price and the percentage off is crucial for determining the final cost. In this scenario, we're looking at an item that is 30 percent off its original price of $40.
Understanding the Calculation
To calculate the discount, we first need to find 30 percent of the original price, which is 40. The formula to find the discount amount is: (percentage off / 100) * original price. Applying this formula, we get (30 / 100) * 40 = 0.3 * 40 = 12.
Applying the Discount
Now that we’ve determined the discount amount is 12, we subtract this from the original price to find the final cost. So, 40 - 12 = 28. This means the item, after applying a 30 percent discount, would cost $28.
| Original Price | Discount Percentage | Discount Amount | Final Price |
|---|---|---|---|
| $40 | 30% | $12 | $28 |

Discounts like these can significantly impact consumer behavior, encouraging purchases and driving sales. For businesses, offering discounts can be a strategic move to clear inventory, promote new products, or simply to attract more customers. Understanding the mechanics of discounts, as demonstrated in this calculation, helps both businesses and consumers navigate the marketplace more effectively.
