Answer questions 17-19 below using the following information: A firm is producing in the short-run (with K fixed at 10 units) according to the following production function: F(L) = Q =10L -0.25L^2 . You also know that w=$15, r=$20 and the firm can sell its product for P=$7.50.
17. To minimize costs how much labor should the firm hire in the short run? a. L=16 b. L=30 c. L=20 d. None is correct
18. How much output Q is produced? a. Q=525 b. Q=300 c. Q=96 d. None is correct
19. How much is the company’s profit? a. Profit=$3287.5 b. Profit=$280 c. Profit=$1750 d. None is correct
Given
P=$7.50
w=$15
K=10
r=$20
17)
Q=10L-0.25L2
Marginal Product of labor=MPL=dQ/dL=10-0.50L
Marginal Revenue product=MRPL=P*(10-0.50L)=7.50*(10-0.50L)=75-3.75L
Set MRPL=wage rate for cost minimization
75-3.75L=15
3.75L=60
L=16
Correct option is
a. L=16
18)
Q=10L-0.25L2=10*16-0.25*16^2=96
Correct option is
c) Q=96
19)
Total Cost=rK+wL=20*10+15*16=$440
Total Revenue=P*Q=7.50*96=$720
Profit=Total Revenue-Total Cost=720-440=$280
Correct option is
b) $280
Answer questions 17-19 below using the following information: A firm is producing in the short-run (with...
Suppose that a firm is producing in the short run with output given by: Q = 75L-L2 The firm hires laborat a wage of $32 per hour and sells the good in a competitive market at P = $24 per unit. Now suppose that a firm is looking to maximize Total Revenue (not Total Profit) How many workers (L) should the firm hire? Enter as a value. ROUND TO THE NEAREST WHOLE NUMBER.
c. Using the firm's information shown below answer the followin Q = f(KL) = 10KL r = $40 W = $25 MPK = 10L MPL = 10K D. In the short run if the firm's capital is fixed at 25 units, how much will it cost them them to produce E. What will the firm do in the long run to minimize the cost of producing Q = 500? F. What are the firm's cost savings from the short-run (part...
[Short-Run Production] Suppose that a firm is producing in the short run with output given by: Q = 200.5L – 2.5L2, The firm hires labor at a wage of $25 per hour and sells the good in a competitive market at P = $50 per unit. Find the firm’s optimal use of labor and associated level of output. (For extra practice, what is the firm’s associated profit?) I have already finished and went to check my work on Chegg and...
2) (4 points) Suppose that a firm is producing in the short run using a combination of labor and capital. At their current point of production, the MPL = 100, MPK = 6000, w = $25 and r = $2000. In the long run, is the firm minimizing costs? If not, how should they change around their use of K and L to minimize costs while producing the same quantity? Discuss.
Draw a diagram below that shows the short run profit maximizing output for a competitive firm at a market price of S10 producing an output of 20 that leads to a profit of $40. 4. 5. If SMC-20+2Q, AVC-1.5Q, P $100. a. Find Q b. This perfectly competitive firm will break-even if fixed cost equal how much?

In a perfectly competitive market, a firm has the following short-run total cost function: C(q)=16+4q+q2 The market demand is Q(p)=220-p a. Show that marginal cost curve passes through the minimum point of average cost curve. Draw a figure to show it. b. Find the firm’s individual short-run supply function. Draw it on the above figure. For the following questions, suppose that there are currently 10 identical firms in this market. c. What is the market supply curve? What are the...
The graph below shows a firm's isoquants and isocosts. The firm is initially producing Q-20 with the cost minimizing combination of K and L, where Q is output, Kis capital and Lis labor. Suppose the owner decides to expand production to Q=40. However, he signed a lease on the capital necessary to produce Q=20, which he cannot get out of in the short run. Are the short run total costs of producing Q-40 smaller or larger than the long run...
