Well, as I remember the law of demand states the bigger the demand the bigger the price.
Or something along these lines, this is just the basic principle as you already know.

I don't know the math part of it though, because i can't really see everything well on the attachment.

Looks abstruse to me, because it doesn't seem to indicate what the units are in the question, yet it doesn't look like one unit is just 1 dollar.
