3K 4 Suppose that a production function is given by F(L,K) = L " K " in which case the marginal products will be given by MPL = and 4L MPK = L , respectively. What is the marginal rate of technical substitution at (L,K) = (18,3), and what is the interpretation? 4K O N - which means that in order to maintain the same level of output, then if you increase K by one unit, you must decrease _ by two units. O -2, which means that in order to maintain the same level of output, then if you decrease _ by one unit, you must increase K by two units. O N - which means that in order to maintain the same level of output, then if you increase K by one unit, you must decrease L by two units. O 2, which means that in order to maintain the same level of output, then if you decrease L by one unit, you must increase K by two units
