Question 3:
Suppose a firm has the following production function:
Q(L, K) = 2L + K
Recall that the isocost line is as follows:
C=wL+rK
1. What is the (long-run ) optimal choice of L and
K for a given Q, w, and r? In other words,
provide a formula for the optimal choice of labor
L* (w, r, Q) and capital K* (w, r, Q) as a
function of the parameters Q, w, and r.
2. Given Q = 20, w = 6, and r = = 1, what are L*
and K*?
