This is one of those questions where you can utilize the answer choices to answer the question. Simply, the formula would be $$649-649x$$ where x is the percentage off. By doing this, you find out how much money is discounted and find your price with the discount.

If you want to do this legitimately, simply use the formula as shown, but with one edit.$$649-649x=519.2$$
Simply combine like terms and divide. Then you have your discount value.
