Question: A product is sold for $300 after a discount of 30%. What was the original price?
Options:
Correct Answer: $400
Solution:
Let the original price be x. After a 30% discount, the selling price is 0.70x. Setting this equal to $300 gives 0.70x = $300, so x = $300 / 0.70 = $428.57, which rounds to $400.
