The profit of a firm is the excess revenue left with the firm after deducting the total cost of production from the total revenue of the firm that is generated through the sale of the goods and services. Here, in the case of the firm, the case is
Here, the monopoly price is higher than the competitive price; this means that the firm earns higher than the marginal cost and the average cost (which is the profit per unit). When it is multiplied with the monopoly quantity, it gives us the profit of the monopolist.
Concept introduction:
Cartel: A cartel is an association or organization of suppliers or producers, which has the main intention of keeping the prices of the commodities that they produce high and reducing the competition between them.
Market: The market is a structure where there are buyers who buy and sellers who sell and there is an exchange of goods and services between them. The price is determined by the interaction of demand and supply in the market.
Subpart (b):
The lure of the cartels.
Subpart (b):

Explanation of Solution
When the size of the monopoly profit has to be calculated, the area can be calculated by subtracting the average cost of the firm (which is also equal to the marginal cost) and competitive price from the monopoly price, and multiplying it with the monopoly quantity. It is the area of the monopoly profit which can be explained in the following formula:

The lure of the cartels.
Subpart (c):

Explanation of Solution
It is given that the monopoly price is equal to $0.70/lb and the marginal cost of production (which is equal to the average cost of production and the competitive price) is $0.40/lb. The monopoly quantity demanded is given as 300 million lb. Thus, the monopoly profit per unit can be calculated by subtracting the average cost from the monopoly price as follows:
Thus, the monopoly profit per unit is $0.30/lb. Similarly, the total industry profit can be calculated by multiplying the monopoly per unit profit with the total monopoly quantity demanded as follows:
Thus, the total industry profit is equal to $90,000,000.

Subpart (d):
The lure of the cartels.
Subpart (d):

Explanation of Solution
When the monopoly market is in operation, each producer earns $0.30/lb of apples. When everything remains the same and one single producer cheats the cartel by increasing the production by 1,000,000 pounds of apples, it will increase the profit of the producer. This can be calculated by multiplying the per-unit profit with the increased quantity as follows:
Thus, the cheating producer earns approximately $300,000 additionally, through cheating. The extra profit made is approximate because the increase in the quantity will push the prices down in the market. Since the increase in the quantity is only 1/300th of the market, the impact on the price would be lower.

- 1. A doctor quits his job, which pays $77,000 per annum, to open a non-governmental organization (NGO) to serve the needs of orphans. His annual expenses for the NGO amounts to $62,700 for food and daily supplies, $9,400 for maintenance, and $1,800 for books. What is his opportunity cost of opening the NGO? (Show working) 2.

Samuelson We are now in the "blame phase" of the economic cycle. As the housing slump deepens and financial markets swing erratically, we've embarked on the usual search for culprits. Who got us into this mess? Our investigations will doubtlessly reveal, as they already have, much wishful thinking and miscalculation. They will also find incompetence, predatory behavior and probably some criminality. But let me suggest that, though inevitable and necessary, this exercise is also simplistic and deceptive. -- business It assumes that, absent mistakes and misdeeds, we might remain in a permanent paradise of powerful income and wealth growth. The reality, I think, is that the economy follows its own Catch-22: By taking prosperity for granted, people perversely subvert prosperity.
