Solve these pliz

A firm manufactures quad bikes ("quads"). Each quad is made using one frame (x ,) and four wheels (x 2). Each frame costs $10 and each wheel costs $4. The output of the firm can hence be represented by the function min x17X2 (Hint: this is similar to working with min |K, -4 , but instead of considering prices r and w you may consider prices p, and pz for the inputs) a) What is an isoquant? Show the isoquants for producing two quads, three quads and seven quads. [5 marks] b) Derive the input demands for frames and wheels for the firm. How do they de- pend on the input prices? What is the maximum number of quads the firm can produce if the number of wheels is fixed at 12? Assume that the firm is produc- ing the maximum number of quads. What is the marginal product of adding an extra frame? [10 marks] c) Define the firm's cost function and derive it. Assume that each wheel costs E4 and each frame costs $10. What is the cost of producing 7 quads? [5 marks] d) Assume that the firm needs to pay $50 per day to rent the factory to produce quads (this is a fixed cost). Continue to assume that each wheel costs $4 and each frame costs $10. Suppose that the firm can only produce 10 quads per day and the rent has already been paid for today. If the price at which the firm can sell quads is $30 should the firm produce today? Explain your reasoning. [5 marks] e) Continue to assume that the daily rent is E50, each wheel costs E4 and each frame costs $10. Suppose that the firm can only produce 10 quads per day and the rent can be stopped (so the cost of producing zero quads is zero). If the price at which the firm can sell quads is E30 should the firm produce today?(a) Consider an industry served by two firms, say firm 1 and firm 2, that sell identical goods. The firms set prices P, and P2 simultaneously to maximise profits and each firms has constant marginal costs of production. Suppose that marginal costs are C1 = 62 = c, 0 P2 D(P]) = 10 - if P1 = P2 4 P1 20 - if P1 P1 D(P2) = 10 - - P2 if P = P2 4 20 - _2 if P2
