1.5 Setting p = ATC, and then solving for q = 8.8730.
q = = 8.8730
2.1 p = $100
2.2 p = $100, Q0 = 2500, q = 10, (the number of firms) n0 = 250, (profit) π = 0. 2.3Setting ATC = SMC, q = 10
2.4 The short-run supply function for each firm is q = p / 10, and the industry short-run supply function is Qs = (n) q = 250 p / 10 = 25 p
2.5 pvsr = 300
2.6 psr = 133.33, Q = 3,333.33
2.7 p = $100, Q1 = 3500, q = 10, n1 = 350, π = 0
