Answer to Question 1

a. Set MC = AC.
20 = (40,000/Q) + 20
In this case, AC is decreasing everywhere, and thus there is no minimum average cost (although it will approach 20).
Set MC = AVC.
20 = 20
Q = 0, and at that point, AVC = 20.
b. Set MC = AC.
2 + 0.2Q = (1000/Q) + 2 + 0.1Q
Q = 100, and at that point, AC = 22.
Set MC = AVC.
2 + 0.2Q = 2 + 0.1Q
Q = 0, and at that point, AVC = 2.
