A $649 laptop computer cost $519.20 after a coupon is applied. What percentage off is the coupon?
To find the percentage off, we need to calculate the discount first, which is the difference between the original price and the discounted price.
Discount = Original Price - Discounted Price
Discount = $649 - $519.20
Discount = $129.80
Then, we can calculate the percentage off using the following formula:
Percentage Off = (Discount ÷ Original Price) x 100
Percentage Off = ($129.80 ÷ $649) x 100
Percentage Off = 20%
Therefore, the coupon offers a 20% discount on the $649 laptop computer, making the final price $519.20.
