The level of profit that occurs when the total revenue is to the total cost is known as normal profit.

The statement you provided is correct. Normal profit occurs when a firm's total revenue equals its total cost. In this scenario, the business is covering all its expenses, including the opportunity costs of capital and labor.

Explanation:

1. Definition of Normal Profit: Normal profit is considered a form of economic profit. It does not represent a surplus; rather, it signifies a break-even point where the firm is making just enough to cover all explicit costs (wages, rent, cost of goods sold) and implicit costs (the opportunity cost of using resources).

2. Importance in Economics: Normal profit is essential in economics as it indicates that a firm is sustaining itself without making losses or extraordinary profits. It provides a benchmark to assess whether a business is functioning effectively.

3. Market Implications: In a perfectly competitive market, firms tend to earn normal profits in the long run due to free entry and exit of firms. If firms were earning more than normal profits, new firms would enter the market, increasing competition and driving profits down. Conversely, if firms consistently post losses, some will exit the market, which may stabilize or increase profits for those remaining.

In summary, normal profit is a crucial concept in understanding how businesses operate within different economic conditions, and it reflects an equilibrium state in the market.
