Can you help with this DS question?- Thanks in advance!

Stores L and M each sell a certain product at a different regular price. If both stores discount their regular price of the product, is the discount price at Store M less than the discount price at Store L ?

(1) At Store L the discount price is 10 percent less than the regular price; at Store M the discount price is 15 percent less than the regular price.
(2) At Store L the discount price is $5 less than the regular store price; at Store M the discount price is $6 less than the regular price.

I think the answer is C. We need both statements to answer this question. The $5 is 10% of original price of L and $6 is 15% of original price of M. After finding the original prices we can check which discounted price is less.

Then how can we find the two different original prices? There's no way to figure out which discount price is less without knowing their original prices

Hi Yumi,

With BOTH FACTS combined, we know that....

Store L: the $5 discount = 10% of the original price, so the original price = $50
The math:
5 = .1X
50 = X

Store M: the $6 discount = 15% of the original price, so the original price = $40
The math:
6 = .15Y
600 = 15Y
40 = Y
