Referring to Page 2, I'm not quite sure what the author is trying to say regarding the two bracketed portions. Considering the first bracketed portion, when the author says "purchased less than Q0", is the author still referring to a point on the demand schedule line? Also referring to the first bracketed portion, how do we know the consumer "value additional consumption more than its cost to her", and thus purchase more? How do I represent all these graphically?
