10.A perfectly competitive firm has two production techniques to convert labour into output. In the rst technique, the production function is given by y1(ll) = 11/2 1 TC (3/, w) of the producer gives the minimal expenditure required to produce a 1 , and in the second one it is given by y2(lz) = 212/2. The total cost function given total amount of y of the output (i.e., y1 + yz = y) at input price w. a) The firm's conditional demand for 12 is twice as large as the conditional demand for ll. b) If the price of the good per unit is 100 and the labour costs 10 per unit then the rm supplies 25 units of the good. c) The firm cannot be maximising profit because such an output level does not exist. d) The firm will not supply output if the price of the good falls below 20
