I understand this question is very long, but please only answer if you can complete all of it. When I posted it the first time I received a-d, which I am including below. I am not sure if they are correct. Thank you so much in advance!!
A. MPL = dQ/dL = 30 - 2(0.05L) = 30 - 0.1L
B. At L = 200, MPL = 30 - 0.1(200) = 30-20 = 10
C. Output is maximized when MPL=0
So, 30-0.1L = 0
So, 0.1L = 30
So, L = 30/.1 = 300
Lmax = 300
D. Profit is maximized when MRPL = MC
MRPL = MR*MPL= 5*(30-0.1L) = 150 - 0.5L
So, 150-0.5L = 40
So, 0.5L = 150-40 = 110
So, L = 110/.5
Thus, L = 220
The answers from A to D are right.
e) L*=220
Q=30*220-0.05*220*220=4180
So firm will produce 4180 To maximize profit at given good price and wage.
f) Profit=Total revenue - total cost
Total revenue=Price* total quantity=5*4180=20,900
Total cost=Wage* labour=40*220=8800
Profit=20,900-8800=12,100
G)
Profit is maximized when MRP = MC
MRPL = MR*MPL= 5*(30-0.1L) = 150 - 0.5L
So, 150-0.5L = 45
So, 0.5L = 150-45 = 105
So, L = 105/.5
Thus, L *= 210
H)
Profit is maximized when MRP = MC
MRPL = MR*MPL= 8*(30-0.1L) = 240 - 0.8L
So, 240-0.8L = 40
So, 0.8L = 240-40 = 200
So, L = 200/.8
Thus, L* = 250
I) The Increase in wage will shows as a upward movement along labour demand curve .
Increase in marginal Revenue will shows as a shift of labour demand curve to right side.

A production function is given as Q = 21L - 0.06L2. If each unit of output Q contributes $10 in revenue (sells for $10) and each labor unit costs $42 per hour, how many units of labor (L) should be hired to maximize profit? Given your answer to part c, what output (Q) will the firm produce? Assuming no other cost than labor costs, what is the profit at this level of labor and output Suppose that the marginal...
Suppose a short-run production function is described as Q = 1L - (1/800)L2 where L is the number of labors used each hour. The firm's cost of hiring (additional) labor is $20 per hour, which includes all labor costs. The finished product is sold at a constant price of $40 per unit of Q. a. State the firm's MPL: b. How many labor units (L) should the firm employ per hour: c. Given your answer in b, what is the...
Consider a competitive firm that produces bots. Labor (L) and capital (K) are the only two inputs of production; each unit of labor is paid the market wage (w), and each unit of capital is rented at the rental price of capital (r). Output (Y) is therefore a function of labor and capital, or Y = f (K, L), and is sold at the market price (P). The goal of this firm is to maximize profit given the price of...
The production function of the Auto parts firm is given by Q-5L-L, where Q is the units of output and L is the number of labor hours. Each output sells for 100 dollars per unit. The human resources manager estimates that the marginal cost of hiring an extra worker is 50 dollars. How many labor hours should this firm hire? Hint: MPL=5-2 L 1) 2) A frim's production function is given by Q(L)-6L, where Q measures output and L is...
Can you label each one please . (1)A firm in a perfectly competitive market sells all its product (Q) at a constant price (P) of $60. Suppose the total cost function (TC) for this firm is described by the following equation: 2 3 TC(Q) 128+ 690-14Q + Q (a)Form the profit function and determine the output that maximizes the firm's profit.
