Complete Table 2 by calculating the missing values for the marginal cost Jim incurs when producing the last of each of the numbers of pizzas in the table. Explain how you arrived at your figures.

Using the data in the completed Table 2 and the module materials, find the number of pizzas Jim will supply if:

• a.the market price is 11
• b.the market price is 19
• c.the market price is 27.

The points you calculated in your answer to Question 4 are part of Jim's supply curve for pizzas. Plot these three points and briefly describe what they suggest about the relationship between Jim's supply and the market price.

1. In the market there is a second producer of pizzas, Alex. Alex's individual supply curve of pizzas is shown in Table 3. Calculate the total market supply of pizzas based on the assumption that Jim and Alex are the only two producers of pizzas in the market. Use Excel a graph choosing 'Scatter with smooth line and markers' which shows the market supply of plant pots.
