A. P/14
Explanation: C(Q) = 7Q2
So, Marginal cost = d/dQ (7Q2) = 14Q.
In perfect competition, marginal cost = marginal revenie i.e. price
So, P = 14Q
i.e. Q = P/14
A firm operating in a Perfectly Competitive Market has costs equal to C(Q) 7Q which of...
Firm Z, operating in a perfectly competitive market, can sell as much or as little as it wants of a good at a price of $16 per unit. Its cost function is Ce50+ o a) Determine the firm's profit-maximizing level of output. Compute its proft. b) The industry demand curve is Q-200-5P. What is the total market demand at the current $16 price? If all firms in the industry have cost structures identical to that of firm Z, how many...
1. Suppose that a firm operating in perfectly competitive industry has short-run cost function given by C(q) = 5+2q+9. The market price is $10. (a) What is the profit-maximizing output level for this firm? (b) What is the firm's total revenue and profits at the profit-maximizing output? (c) What is the minimum price at which the firm will produce a positive level of output in the short run?

Briefly discuss a strategy a firm operating in a perfectly competitive market must take to sustain its profit outlook. [3 Marks] A firm operating in a competitive market has the following cost function C = 10 + 2Q2. The market demand is Q = 40 – 2P and equilibrium price of output is K20. Calculate the output the firm must to maximize its profits. [3 Marks] Find the price the firm must charge to maximize profits. [2 Marks]
Why are marginal revenue and price equal for a firm operating in a perfectly competitive market?
A firm in a perfectly competitive market has a short-run total cost curve of ST C(Q) = 20 + 10Q + Q2. The market price is $10. a) What is the profit-maximizing quantity? b) What are the maximum profits? c) Find the short-run supply curve if all fixed costs are sunk. d) Find the short-run supply curve if all fixed costs are non-sunk. e) Suppose there are 100 identical firms in this market. What is the market supply curve if...
Suppose you are analyzing a firm operating in a perfectly competitive market. You know the market demand curve is P = 300 - Q and the market supply curve is P = -525 + 2Q. You also know that the cost function of the firm is: C (Q) = -1/6Q^3 - 1/2^2 + 21Q + 100/3. Using this information find A. the quantity that will maximize profits. B. If the firm is making a profit or suffering loss
(d) A perfectly competitive firm has the following production function: Q=L The price of labor is equal to w. If the firm maximizes profit and the price, p, is equal to 4w, then the firm will supply 2 units of output and profit is equal to 4w.
In a perfectly competitive market, a firm has the following short-run total cost function: C(q)=16+4q+q2 The market demand is Q(p)=220-p a. Show that marginal cost curve passes through the minimum point of average cost curve. Draw a figure to show it. b. Find the firm’s individual short-run supply function. Draw it on the above figure. For the following questions, suppose that there are currently 10 identical firms in this market. c. What is the market supply curve? What are the...
