Consider a firm with the following short-run costs:
Quantity Variable Cost Total Cost
1 30 90
2 50 110
3 90 150
4 140 200
5 200 260
Draw the three cost ? explain the relation between MC CURVE AND ATC CURVE ?
ALSO THE RELATIONSHIP BETWEEN AVC CURVE AND ATC CURVE?
Marginal cost is the additions made to total cost for every additional unit produced. It is computed as change in TC / change in Q. AVC is VC/Q and ATC is TC/Q
The graph is drawn below. We see that MC and AVC as well as MC and ATC display three features

1. Draw two graphs. On the first, show the short-run profit maximizing output of an individual firm earning an economic profit, including MR, MC, AVC, and ATC. On the second, show the short-run market equilibrium price and quantity. Explain how the industry supply curve and the market equilibrium price and quantity are determined. 2. What is the relationship between the price on the two graphs? Why does this relationship exist? 3. Explain why a firm in a perfectly competitive industry...
