(e) Use Lagrange multipliers to find the maximum value of (f) z = x + 4xy subject to the constraint x + 3y = 5 A profit-maximising firm has a marginal cost function and a marginal revenue function given by MC = 3x+10x + 10 and MR = 6x - 17 respectively. i. ii. Using the tools of integration, find an expression for [8 marks] firm's total revenue and total cost function in terms [14 marks] of Q. Find the profit-maximising level of output if firm's fixed cost of production are zero.
