E. A producer has two production processes, both using a single input, r, and both producing thesame output, y. The first one produces output according to fi(21) = 120z, the second oneproduces output according to fa(r2) = 10r. The producer is in a competitive industry, and takesas given p, the price of y, and w, the price of r.E.1. Give the firm's cost function.1/3E.2. Give the range of p's and w's for which the firm's supply function can be found, and explainwhy it cannot be found outside of that range.E.3. Give the firm's supply function, its input demand function, and its profit function over therange where these are defined.E.4. Using the envelope theorem, give the derivative of the firm's profit function with respect top and with respect to w.

Assume that a competitive firm has the total cost function: TC=1q3−40q2+820q+1900TC=1q3-40q2+820q+1900 Suppose the price of the firm's output (sold in integer units) is $650 per unit. Using tables (but not calculus) to find a solution, what is the total profit at the optimal output level? Please specify your answer as an integer.
In competitive markets, there are many small firms with each firm unable to influence the market price. Suppose company ABX operates in the wheat market. The company produces and markets wheats at a Price = $20 per container. The firm’s total costs are given as: TC = 50 +2Q + 3Q2 What is the firm’s demand curve? Show it on a graph and label the axes showing P and Q
Is Consider the daily market for hot dogs in a small city. Suppose that this market is in long-run competitive equilibrium with many hot dog stands in the city, each one selling the same kind of hot dogs. Therefore, each vendor is a price taker and possesses no market power. The following graph shows the demand (D) and supply (S = MC) curves in the market for hot dogs. Place the black point (plus symbol) on the graph to indicate the market price and quantity that will result from competition. (?)

This firm buys up all the rest of the hot dog vendors in the city and operates as a monopoly. Assume that this change doesn't affect demand and that the new monopoly's marginal cost…

Under conditions of perfect or pure competition, or close to those conditions, producers (firms) are what are called “price takers”. This means that the price for the product that they are selling is determined by the market. No matter how little or how much product they supply, they can sell all they want at that price. If they were to price their product higher, they will sell zero. Which of the following is true? The price is equal to marginal revenue but not average revenue The price is equal to marginal revenue and average revenue The price is equal to average revenue but is not equal to marginal revenue The price is above both marginal revenue and average revenue

Long Run Equilibrium Consider a perfect competitive market with n identical firms. The cost functions of an individual firm are: The market demand is given by TC=q³ - 4q² + 74q MC=3q² - 8q+74. P= 120-Q a) In the above space draw two graphs one for the market and one for the firm to show the long run equilibrium b) In the long run, each firm will produce q.. i.e. the firm is operating at its minimum c) The long run equilibrium price must be P=. d) Thus the total amount purchased will be Q= e) This means there is enough room for n=. f) No more entry will take place because.. g) Show all equilibrium values on your graph ..firms Because. because..
Total cost function in competitive firm is TC = 27+ 3Q2. If firm gets normal profit please find the average total cost of this firm.
