An economist estimated that the cost function of a single-product certain is:C(Q) = 90 + 35Q + 25Q^2 + 10Q^3.Based ~ above this information, identify the following:a. The fixed expense of developing 10 devices of output.b. The variable price of producing 10 units of output.c. The complete cost of developing 10 devices of output.d. The typical fixed expense of creating 10 devices of output.e. The median variable price of developing 10 devices of output.f. The average complete cost of creating 10 units of output.g. The marginal expense when Q = 10.

You are watching: An economist estimated that the cost function of a single-product firm is:

a. Answer is 90 asb. Replace Q v 10. 90+35(10)+25(10)^2+10(10)^3-90 = 12,850c. Variable cost - solved cost, or 12,850-90 = 12,760d. Fixed price / quantity, or 90/10 = 9e. Variable expense / quantity, or 12,850/10 = 1285f. Typical fixed expense + median variable cost, or 1285+9 = 1294g. Take part of the original equation, take the power number and multiply by the number that effects, then mitigate the power number through 1. 35Q + 25Q^2 + 10Q^3 becomes35 + 50Q + 30Q^2. Since Q = 10, settle for answer: 3535
A manager rental labor and rents funding equipment in a really competitive market. Right now the wage rate is $8 per hour and also capital is rented in ~ $12 per hour. If the marginal product of labor is 60 systems of output per hour and also the marginal product of resources is 50 systems of output per hour, need to the for sure increase, decrease, or leave the same the quantity of capital used in its manufacturing process?
A firm"s product sells for $4 per unit in a very competitive market. The for sure produces output using funding (which it leas at $25 per hour) and labor (which is paid a fairy of $30 every hour under a contract for 20 hours of job services). Finish the adhering to table and use that info to answer the concerns that follow.
Working notes:(1) MPK = change in output (Q) / adjust in K(2) APK = Q / K and also APL = Q / L(3) VMPK = MPK x Price = 4 x MPK(4) complete cost = wL + rKWhen Q = 0, TC = Fixed cost (FC)So, FC = 20 x $30 = $600(5) benefit = (P x Q) - TC = 4Q - (wL + rK) = 4Q - 600 - 25K
A firm have the right to manufacture a product follow to the production function:Q = F(K,L) = K^3/4 L^1/4.a. Calculate the mean product that labor, APL, as soon as the level of capital is fixed at 81 units and also the firm uses 16 devices of labor.b. Discover an expression for the marginal product the labor, MPL, once the lot of capital is resolved at 81 units.Then, show that the marginal product the labor relies on the lot of job hired through calculating the marginal product of job for 16 and 81 units of labor.c. Suppose funding is solved at 81 units. If the firm can sell its calculation at a price the $200 per unit and can hire labor at $50 every unit, how plenty of units of labor should the firm rental in order come maximize profits?
a) once K = 81 &(1) together = 16.Q = (81)3/4 x (16)1/4 = 27 x 2 = 54APL = Q / together = 54 / 16 = 3.375(ii) l = 256Q = (81)3/4 x (256)1/4 = 27 x 4 = 108APL = Q / l = 108 / 256 = 0.422(b) MPL = dQ / dL = (1/4) x K3/4L-3/4(i) when K = 81, MPL = (1/4) x (81)3/4L-3/4 = (1/4) x 3 x L-3/4 = 0.75 x L-3/4(ii)When together = 16, MPL = 0.75 x (1/8) = 0.0938When l = 81, MPL = 0.75 x (1/27) = 0.028As l increases, MPL decreases. So MPL counts on L.(c)Firm should hire job upto that suggest where Price x MPL = fairy rateWhen K = 81, MPL = 0.75 x L-3/4$200 x 0.75 x L-3/4 = $50L3/4 = 3Raising every side to (4/3)rd power,L = 4
