3. Total, average, and marginal physical product Underground Sandwiches, a sandwich shop, has the following marginal physical product curve (labeled MPP) for ii: hourly production. Note: Marginal values are sometimes plotted between integers (to indicate that they represent changes incurred in moving from one integer to the next), and sometimes they are plotted directly on the integers with which they are associated. For the context of this graph, they are plotted between integers. For example, if the marginal physical product from one unit of labor to two is x, this point is plotted at (1.5, 3:). 20 13 C 15 APP 3 O f 14 3 W E 12 .9 3 4: 10 {B Q & 8 e: g s & E 4 MPP 2 o i I I I i a 1 2 3 4 5 QUANTITY OF LABOR when labor increases from two to three workers, total physical product decreases V by 3 sandwiches V per hour. r Use the orange points (square symbol) to plot the total physical product curve on the following graph. Assume that if there are no workers, Underground Sandwiches does not produce output. Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically. 60 54 TPP 48 42 36 TOTAL OUTPUT (Sandwiches per hour) 30 24 12 0 3 QUANTITY OF LABOR On the graph showing the marginal physical product (MPP) curve, use the purple points (diamond symbol) to plot the average physical product curve (APP) at one, two, three, four, and five workers. The marginal physical product (MPP) curve and average physical product (APP) curve intersect at the maximum * of the average physical product _ curve
