The profit maximizing level of output for this farmer is

Question

Quizplus · Accepted Answer

The profit maximizing level of output is where MR (marginal revenue) equals MC (marginal cost). 
From the given table, we can calculate the marginal cost (MC) by finding the change in total cost for each additional unit of output. For example, to produce 6 units, the total cost is $40, and to produce 9 units, the total cost is $60. This means the marginal cost of producing the 3rd unit is $20 (the difference between $60 and $40). 
Similarly, we can find the marginal revenue (MR) by looking at the change in total revenue for each additional unit of output.
For example, producing 6 units will generate a revenue of $60, and producing 9 units will generate a revenue of $90. The marginal revenue of the 3rd unit is $30 (the difference between $90 and $60).
Now, we can compare the marginal revenue and marginal cost to find the profit-maximizing output level. 
At 12 units, the marginal revenue is $30, and the marginal cost is $30 as well. Therefore, producing 12 units would maximize the farmer's profit.
