Answer:
70%
$571.41
Step-by-step explanation:
100% means 1, or a whole thing.
Since the discount is 30% of the original price, and the original price is 100% of the original price, then

With a 30% discount, you actually pay 70% of the original price.
<em>$399.99 is 70% of the original price.</em>

x = 571.41
<em>The original price was $571.41.</em>
