Betty and Bob Widget Company employs labor (workers) and uses capital (money) to produce output (widgets). The total weekly output is given by P(L, K) = 20K + 32L +3LK -2L^2 -2.5K^2 where L is the number of labor units and K is the number of capital units. a. Find the critical point for P. It is L = and K = b. Does this result in a maximum, minimum, or saddle point?
