Schmutz Auto Wash provides car washes. Its production function is ? = 2?1/2(? - 1)1/2
where ? is cars washed per day, ? is daily hours of labor input, and ? is daily usage of capital inputs. The price of a unit of capital input is $48. The price of a unit of labor input is $16. In the short run, Schmutz has 4 units of capital input installed (so ? = 4).

a). Find Schmutz’s short run daily total cost function, short run daily variable cost function, and short run daily fixed costs.

b). Find Schmutz’s short run marginal cost function, short run average variable cost function, and short run total cost function.

c). Suppose that the market for car washes is perfectly competitive and the going market price of a car wash is ?. Find Schmutz’s short run daily supply function, including its shutdown price.

d). Find Schmutz’s short run daily quantity supplied, producer surplus, and profit if ? = 40.

A car wash firm calculates that its daily production (in number of cars washed) depends on the number n of workers it employs according to the formula P = 40n − 0.05n2 cars. Calculate the marginal product of labor at an employment level of 50 workers. HINT [See Example 3.] This means that, at an employment level of 50 workers, the firm's daily production will increase at a rate of  cars per additional worker it hires.

A car wash has two stations, 1 and 2. The service time at station 1 is exponentially distributed with parameter λ1, and the service time at station 2 is exponentially distributed with parameter λ2.When a car arrives at the car wash, it begins service at station 1, provided station 1 is free; otherwise, the car waits until station 1 is available. Upon completing service at station 1, the car then proceeds to station 2, provided station 2 is free; otherwise,...

9.     a. Suppose that a firm’s production function is q=9x^1/2 in the short run, where there are fixed costs of $1000, and x is the variable input whose cost is $4000 per unit. What is the total cost of producing a level of output q? In other words, identify the total cost function C(q). b.   Write down the equation for the supply curve. c.   If price is $1000, how many units will the firm produce? What is the level of...

A competitive firm has the production function Q = (Lw + Lb) 1/2 , where Lw and Lb are the respective numbers of white and black workers employed. The price of output is constant at P = 36. The market wage is wb = 3 for black workers and ww = 9 for white workers. If a firm has a discrimination coefficient of d > 0, then it behaves as if the wage is wb(1 + d) for black workers...
