Answer:
$4000 is the correct answer to the given question .
Explanation:
The marginal cost with compare to the labor can be written as
Here K=9 units putting this value in the previous equation we get
We can find the value of labor by the given formula that are given below
From the given question that are mention in question
Q = 2(K)1/2(L)1/2
Putting the value of K and L in the given equation we get
So profit maximizing output is =$60 chairs as the chairs can be sold for the $400 each so = $60 * $400 *10=$24000 chairs
As the competitive wage of $120 for 100 units as well as the total of $8,000 on the 9 units of capital equipment
=$20000
Therefore profit-maximizing level of output =$24000-$20000=$4000
