Suppose a rm has the production function, Q = 12KL. It has a contract to produce 14-4 units of output per day. One way to do is to use 3 units of capital (K) and 4 units of labor (L). Suppose a unit of labor costs $2 (wage = w) while a unit of capital costs $3 (r). 24. How much would it cost to produce the 144 units using this combination of capital (K = 3) and labor (L = 4)? A) Total Cost of labor and capital expenses would be $27 B) Total Cost of labor and capital expenses would be $19 C) Total Cost of labor and capital expenses would be $17 D) Total Cost of labor and capital expenses would be $15 25. What will be the marginal product of labor (MPL) when K = 3 units and L = 4 units
