1 What is quantity demanded? Suppose you are trying to sell 100 tickets to a student production of the play Romeo and Juliet for $5 each. The quantity demanded is the amount of tickets people are able and willing to buy at the given price. No matter what the ticket price is, some people like Shakespeare a lot and are willing to pay the price. Others wouldn't want to sit through three hours of 16th century English even if the tickets were free. Aside from personal taste, some people can afford the tickets and some people are not able to afford the tickets. Both of these factors, personal taste and financial situations, affect your ticket sales. In order to get feel for the concept of quantity demanded, answer the following questions. 1.
