Final answer:
To evaluate the profitability of a company, compare total revenue and total cost. Use the average cost curve to identify profits and losses, and determine the price at which a firm should continue producing in the short run.
Step-by-step explanation:
Profits in a company can be evaluated by comparing the total revenue and total cost. If the total revenue exceeds the total cost, the company is profitable, and if the total cost exceeds the total revenue, the company is making a loss. The average cost curve can be used to identify profits and losses. The shutdown point is the price at which a firm should continue producing in the short run.
