A $649 laptop computer cost $519.20 after a coupon is applied. What percentage off is the coupon?

1 answer

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.
