could you please help me with this question ?

1. Your rm has the following cost function and marginal cost: 2 a@=%+m+w0 MC=+6 a) (4 Points) Given the market demand Q\"! = 60 2p, mathematically derive the competitive equilibrium. \fc) (4 Points) Suppose that the monopoly can discriminate two groups whose demands are: Qd = 25 - p1 and Q2 =35 - p2. Mathematically derive the new equilibria. Is this efficient? Explain.d) (4 Points) Suppose now that the monopoly can exercise perfect price discrimination. What is the new equi- librium? Is this efficient? Explain
