A monopolist faces a market demand Q(p)=1500-5p and has cost function C(q)=120q. Suppose that the government intervenes the market and splits the monopolist into two firms with cost functions C1(q1)=120q1 and C2(q2)=120q2. If the newly created firms compete in Cournot model, then the total output level from both firms in Cournot equilibrium is? 0 600 300 O 450 O 700 560
