It's straight E. Even though when combined we know that x=15 and y=10, this is still insufficient to answer the question. Everything is in percents, the price can be anything.

I know it is not hard at all, I just wanted to see if I was setting it up correctly. $$P = L - \frac{x}{100}L$$ and $$S=L-\frac{y}{100}L$$? P = purchase price, S - selling price and L - list price. Do my equations look ok and is this the way you would set the initial information up? Thanks.
