With a coupon for 20% off, the regular price is $48. How much is the sale price?
The Correct Answer and Explanation is :
To calculate the sale price after applying a 20% off coupon to a regular price of $48, we can follow these steps:
- Calculate the Discount Amount:
First, we need to find out how much the discount is in dollars. Since the discount is 20%, we multiply the regular price by 20% (or 0.20): [
\text{Discount} = \text{Regular Price} \times \text{Discount Rate} = 48 \times 0.20 = 9.60
] Thus, the discount amount is $9.60. - Subtract the Discount from the Regular Price:
Next, we subtract the discount from the regular price to find the sale price: [
\text{Sale Price} = \text{Regular Price} – \text{Discount} = 48 – 9.60 = 38.40
] Therefore, the sale price after applying the coupon is $38.40.
Explanation:
When shopping, coupons are commonly used to reduce the total cost of items. In this scenario, we started with a regular price of $48. By applying a 20% discount, we calculated how much money would be taken off the price. Discounts can be expressed in percentage terms, which means they represent a portion of the total price.
The first step involves converting the percentage into a decimal format, which allows us to multiply it by the price directly. Multiplying $48 by 0.20 gives us the actual dollar amount saved, which in this case is $9.60.
Once we know the discount amount, we simply subtract that from the original price to arrive at the final sale price. This method is straightforward and can be applied to any percentage discount, making it a valuable skill for budgeting and shopping.
In summary, applying a 20% discount to a regular price of $48 results in a sale price of $38.40 after a discount of $9.60 is deducted.
