1. A firm has a production function y = KVL, where K, L are positive quantities of capital and labor and y is the quantity of output. Given a positive input prices r for K and w for L, a producer attempts to minimize the cost of producing output y. Assume that w is fixed at 1 for the duration of production planning. 2 (a) Find C(r,y), the minimum cost of producing y as a function of r and output level y. (b) Compute for C(r, y), and C(r, y) and interpret them.
