Only if you assume the demand curve is linear, which is a poor assumption, as real world markets usually don't have linear demand curves. A $50 price drop from $400 to $350 is not going to have the same effect as a $50 price drop from $350 to $300 or $300 to $250. The following graph illustrates what a real-world demand curve might look like.
