4 Suppose a manufacturing firm is equipped to produce pacemakers and stents. The table below shows provides six possible production possibilities that the manufacturing firm can produce from its available resources and technology during the year. Pacemakers Stents A 100 0 B 90 10 C 70 25 D 40 36 E 10 42 F 0 45 Required: 1. Draw the production possibilities curve (PPC) for the manufacturing plant (put pacemakers on the x axis). (1 mark) 2. What does a PPC show? What are the assumptions about resources and technology in the PPC model? (1 mark) 3. Suppose the manufacturing plant is currently producing as combination C. If the manufacturing plant chooses to produce at combination B, what is the opportunity cost of moving from combination C to B? (1 mark) 4. Suppose the manufacturing plant is currently producing at combination C. If the manufacturing plant chooses to produce at combination D, what is the opportunity cost of moving from combination C to D? (1 mark)
