# Which of the following expressions is correct for a competitive firm?

## Perfect competition short run (1 of 2)- old version

A supply function is a mathematical expression that depicts the relationship between the quantity of a good or service demanded, its price, and other deterministic factors such as production costs, substitute prices, and so on. The quantity supplied is the dependent variable, while the related variables are independent.
The cost curves in a free market find the optimum output point. This is the stage at which expenses are held to a minimum while profits are maximized. The supply curves of individual companies are all positively sloped. As a result, as the price increases, so does the supply. The quantity supplied is determined by market prices, while the price is determined by the quantity available on the market.
As a result, no supply curve determines the optimum production level or price. The optimum output in this case is determined by the output levels that maximize income. When marginal revenue equals marginal cost in a monopoly market, profit is maximized, i.e. MR=MC.
Oligopolies’ supply functions are often poorly described. As a result, deciding the optimal points of an oligopoly without considering demand conditions is difficult. Competitors’ tactics must be taken into account.

## Perfect competition: solving for the market supply curve

Assume a company in a competitive market made \$1,000 in gross sales with a marginal profit of \$10 on the last unit produced and sold. How much did each unit cost on average, and how many were sold?
When a profit-maximizing competitive firm is unable to gain a positive profit, the task of reducing losses is achieved by generating the quantity at which price equals cost.
When the price of A increases to \$14, the company makes whatever changes are required to maximize profit at the new price. Which of the following claims is valid after the firm has adjusted? The competitive firm has been selling its production at \$10 per unit to maximize profit. Then there’s the cost.
Mrs. Smith runs a company in a crowded marketplace. The actual selling price is \$8.50, and the average variable cost is \$8.00, and the average overall cost is \$8.25 at her profit-maximizing level of output.
Find a dynamic market with many similar companies. This market’s firms don’t use any commodities that are only available in small amounts. Market price is stable in the long run.

### How to calculate marginal cost, average total cost, average

Profits are the target of any corporation, whether it is a company that manufactures products or one that provides services. Accounting benefit and economic profit are the two types of profits. In order to make a profit, the producer’s costs are deducted from the sales.
You’ll learn what accounting profit is and why it’s relevant in finance and business in this tutorial. You’ll also learn some basic terminologies and look at some of the more popular financial statements that provide accounting benefit.
In this lesson, you’ll learn what economic profit is and how it varies from traditional accounting profit. Study the formula for estimating economic profit and why a positive accounting profit and a negative economic profit are both possible.
In economics, a surplus is frequently a positive thing. You’ll learn what an economic surplus is and some relevant concepts in this class. After the lecture, you’ll have the opportunity to test your knowledge with a quick quiz.
To gain a strong market share, a company could undercut its competitors’ pricing. You’ll hear about penetration pricing strategy in this class. You’ll also have the opportunity to test your skills with a short quiz.

### Cobb-douglas production function differentiation example

A perfectly competitive firm cannot select the price it charges because the price for its products is dictated by the product’s market demand and supply. Rather, a perfectly competitive firm has the option of selling any quantity of output at the same price. This means that the firm’s commodity has a perfectly elastic demand curve, meaning that consumers are willing to pay the market price for any amount of units of production. When a perfectly competitive firm decides how much to produce, the amount, along with the market prices for production and inputs, determines the firm’s overall sales, total costs, and, eventually, profit margins.
If a company is perfectly competitive, it can sell as much as it wants as long as it respects the current market price. Depending on the price of the product and the number of units sold, total sales will rise as the company sells more. Total revenue would rise if you increase the amount of units sold at a given price. When the price of a commodity rises with each unit sold, the overall revenue rises as well.
