a. Pure monopoly
2) There is no control over price by firms in:
a. Pure competition
3) Which is true under conditions of pure competition?
a. A large number of firms
b. Standardized product (meaning no product differentiation)
c. Price takers (no exertion over product price)
d. Free entry and exit in and out of the market
e. Individual firms have a perfectly elastic demand curve, but whole industries that represent a market do not have a perfectly elastic curve (market demand)
f. Ask Kaibara
4) Competitive firms are assumed to:
a. See Problem 3
b. Ask Kaibara
5) The demand curve faced by a purely competitive firm:
a. Is completely

This is also where AVC (average variable cost) is at its minimum.
18) Refer to the above graph. The level of output at which this firm is maximizing an economic profit is:
a. Point C, where (P = MR) = MC
Use the following to answer question 19: The table shows cost data for a firm that is selling in a purely competitive market.

19) Refer to the above cost chart. If the marginal revenue is $6, what output level will the firm produce?
a. 14 units of output
20) The individual firm’s short-run supply curve is that part of its:
a. Marginal cost curve that either equals or is above the average variable cost curve.
i. (If you look at the graph for Problems 16, 17, and 18, it’s at point A.) ii. (Anything below that point would mean no output or quantity.)
Use the following to answer question 21:
21) Refer to the graph on the left. To maximize profits, this firm would produce:
a. Profit Maximizing Rule: MR = MC
b. Point H
Use the following to answer question 22:
22) Based on the graph on the left, the firm is earning:
a. Zero economic profits.
b. Ask Kaibara
Use the following to answer questions 23 and 24:
23) Refer to the graph on the left. It represents a profit-maximizing firm producing under conditions of pure competition. When the firm is in
Scholastic Dishonesty Acts prohibited by the college for which discipline may be administered include scholastic dishonesty, including but not limited to cheating on an exam or quiz, plagiarizing, and unauthorized collaboration with another in preparing outside work. Academic work submitted by students shall be the result of their thought, research or self-expression.

Students with Disabilities Each ACC campus offers support services for students with documented physical or psychological disabilities. Students with disabilities must request reasonable accommodations through the Office for Students with Disabilities on the campus where they expect to take the majority of their classes. Students are encouraged to do this three weeks before the start of the semester.
30. According to the figure below, if the firm is maximizing profits, profit is represented by the area:
A 13. D 14. B 15. D 16. D 17.
What happen with firm’s price and revenue operating in competitive market if the firm doubles the amount of output it sells?
Assume that next year management wants the company to earn a minimum profit of $162,000. How many units be sold to meet this target profit figure? [3 points]
z. P2) High profits are the signal that consumers want more of the output of the industry.
* Use the profit maximization rule MR = MC to determine your optimal price and optimal output level now that you have market power. Compare these values with the values you generated in Assignment 1. Determine whether your price higher is or lower.)
Perfect competition is an idealised market structure theory used in economics to show the market under a high degree of competition given certain conditions. This essay aims to outline the assumptions and distinctive features that form the perfectly competitive model and how this model can be used to explain short term and long term behaviour of a perfectly competitive firm aiming to maximise profits and the implications of enhancing these profits further.
2. The productivity of making product decreased; however, the price of the product increased thus they are increasing profit. Thus,
11) By how much would the profit contribution of product A has to increase before it will be profitable to produce A?
a. Assuming the most current operational cost levels, what sales must it generate to recoup the above investment?
3) Based on the data in Exhibit 7 and the definition of operating income gains given
