You are using basic demand formula. Percentage of price increase is also relative to demand.

But only in a limited way. Take a look again to the example I gave you with a more expensive PS4. And there is no "formula", you are making the percentage point way too important to strengthen your message which doesn't make it more true.

have you taken economics?
EDIT: Difference in price variation literally means that demand is higher. I would even argue that ps4 price would be higher! But the substitue item is priced at 600. This, according to price elasticity of demand, means that at 600$ the price becomes inelastic, and demand drops.
