In order to derive Lily's demand curve for bananas, we need to solve the buyer's problem for her multiple times and find the optimal number of bananas, when price of a bananas is at a different level each time.
Explanation:
The demand curve is an intractable economic diagram that indicates the connection between an overall market demand for commodity quantity and market price.
The market demand graph is the convergence of all private market demand curves. This indicates the quantity expected by all people at different prices. For eg, the quantity expected by all advertisers at 10 dollars per day is 150 lattes.
