Suppose that Van and Amy are the only suppliers of pizza slices in a particular market. The following table shows their annual supply schedules: Price Van's Quantity Supplied Amy's Quantity Supplied (Dollars per slice) (Slices) (Slices) 20 15 35 25 45 UI A W N 30 50 35 55 On the following graph, plot Van's supply of pizza slices using the green points (triangle symbol). Next, plot Amy's supply of pizza slices using the purple points (diamond symbol). Finally, plot the market supply of pizza slices using the orange points (square symbol). Van's Supply Amy's Supply PRICE (Dollars per slice) Market Supply 20 40 60 80 100 120 QUANTITY (Slices) Now, suppose that Amy's twin brother, who has an identical cost structure and pizza slices supply curve as Amy, moves to the area, adding another producer to this market. As a result, there will be a the market supply curve because there will be a change in quantity supplied
