A firm uses two inputs, X1 and X2, to produce a good that is described by the production function: Q = f (X1, X2) = X1/2X1/4 12 The firm sells its output at $80 per unit: P = $ 80. The cost of input 1, X1, is $4. The cost of input 2. X2, is $2. (a) Solve for the profit - maximizing input mix, output, and profit. (b) Check the second-order conditions to verify that the profit is at a maximum
