Production function = F(L,K) = Q = 4 (LK)0.5
K = 2
w = 4
r = 16
q = 4(LK)0.5
q = 4(2L)0.5
Squaring on both sides
q2 = 32L
L = q2/32
Total cost function = Variable cost + Fixed cost
Variable cost = WL
Fixed cost = rK
TC = wL + rK
TC = (4*q2/32)+(16*2)
TC = 0.125q2+32
Marginal cost function = MC = d(TC)/dq
MC = d(0.125q2+32)/dq
MC = 0.25q
Answer: d

A firm's production function is when $50 has been paid, and zero otherwise. The unit prices of capital and labor are r = $27 and w = $4, respectively. This firm's long-run total cost function is: Score: 1 of 1 2. Suppose the capital input is fixed in the short-run at the level for the firm in question 1. What is the output level at which this capital amount is the long-run choice? Q = 53 Q = 12 Q...
The production function of producing computer software diskettes (Q) is given as: q=LK^1/2. The input K is fixed at 100. The price of K is $2 and the price of L is $50. The short run total cost function is: TC= ___+___*Q, where Q is the Level of ouput.
7. A firm has the production function Q=LK. The firm initially faces input prices w = $1 and r = $1 and is required to produce Q=100 units. Later the price of labor w goes up to $4. Find the optimal input combinations for each set of prices and use these to calculate the firm's price elasticity of demand for labor over this range of prices.
