1. TC = 35 + 5Q 2Q2 + 2Q3 , TC = total costFind (a) the MC (marginal cost) and (b) the AC (average cost). Evaluate them at Q=3 and Q=5.2. Find the MR (marginal revenue) function, Q = 36 - 2P, and evaluate them at Q=4 and Q=10.3. Given C = 2000 + 0.9Yd, where Yd = Y-T and T = 300+0.2Y, use the derivative to find the MPC (marginal propensity to consume).4. Given the total revenue and total cost functions as follow, find the quantity that maximizes the firm's profits.TR = 1400Q - 7.5Q2TC = Q3- 6Q2 + 140Q + 750
