Consider the market for ice cream. Suppose that this market is perfectly competitive. The cost structure of the typical ice cream producer is as follows. Average total cost is equal to ATC(Q) : 1 50 + ÷Q, average variable cost is equal to AVC(Q) =÷Q, and marginal cost is equal to MC(Q) = Q. %3D How many ice cream cones will each producer sell in a long-run equilibrium in the market for ice cream?

You are the owner of a firm in a perfectly competitive market. The market supply and demand are given by the equations: D: P=8 - 0.1Q S: P = 0.2 + 0.05Q Your firm's marginal cost curve and total cost curve are: MC = 0.1 + 0. 2q TC = 20.425 + 0. 1q +0.1q? What is the firm's profit (positive) or loss (negative) ? O 2.2 (profit) O 18.225 (profit) O -18.225 (loss) -2.2 (loss)

A perfectly competitive firm produces the level of output at which MR=MC on the rising portion of the firm’s marginal cost curve. At that output level, it has the following costs and revenues:             TC = $830,000             VC = $525,000             TR = $428,000   Given that the firm produces the level of output at which MR=MC, calculate the amount of profit (loss) this firm earns. is it Profit=TR-TC?

Your Uncle plans to open a business that will operate five stores in the Mississauga area. Four of these firms will operate with production functions q = K1/4L1/4 while the fifth store, the Heartland Superstore will have production function q = 2K^(1/4)L^(1/4). a. Derive the long-run marginal cost curve for the business. (all five stores combined). b. He will be paying competitively determined input prices of PL = $16 and PK = $1 and can sell output for P = $32. (Do not use this information in Part a.) How many persons should he hire for each store? How many units of capital should be installed in each store? Calculate his profits.

Suppose Madison operates a handicraft pop-up retail shop that sells rompers. Assume a perfectly competitive market structure for rompers with a market price equal to $20 per romper. The following graph shows Madison's total cost curve. Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for rompers for quantities zero through seven (including zero and seven) that Madison produces.

Consider a perfectly competitive market where all firms produce using the same technology. In the long run the equilibrium price equals (Need help? Read chapter 4.6 of the textbook, here: https://playconomics.com/textbooks/view/playconomics4-2019t3/part2/ch4/s6) the Fixed Cost. the minimum Marginal Cost. the minimum Average Total Cost. the maximum Average Variable Cost. None of these.

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.

Profit maximization using total cost and total revenue curves Suppose Caroline runs a small business that manufactures shirts. Assume that the market for shirts is a competitive market, and the market price is $20 per shirt.     The following graph shows Caroline's total cost curve. Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for shirts quantities zero through seven (inclusive) that Caroline produces.         Caroline's profit is maximized when she produces______ shirts. When she does this, the marginal cost of the last shirt she produces is ______, which is (GREATER OR LESS)   than the price Caroline receives for each shirt she sells. The marginal cost of producing an additional shirt (that is, one more shirt than would maximize her profit) is _____, which is  (GREATER OR LESS)  than the price Caroline receives for each shirt she sells. Therefore, Caroline's profit-maximizing quantity corresponds to the…

Suppose Amari operates a handicraft pop-up retail shop that sells phone cases. Assume a perfectly competitive market structure for phone cases with a market price equal to $20 per phone case. The following graph shows Amari's total cost curve.

a) Find the long run equilibrium price.  Find the minimum efficient scale of the typical firm. Find the typical firm’s average cost when it operates at minimum efficient scale. In the long run, what price will prevail in this market? In words, clearly justify your answer. Suppose demand is QD = 3,200 – 100P. (b) Explain why you expect the number of firms in this market to be fifty-five. In this market, what is the short run supply function of the typical firm? What is the short run market supply function? Suppose the local government introduced a $90 licensing fee that raised the fixed cost from $160 to $250. c) Would the introduction of the licensing fee affect the short run equilibrium price or quantity? Justify your answer? Clearly explain why you expect that in the long run fewer larger firms will operate in this market. After the introduction of the licensing fee, what is the new long run equilibrium price? How many firms will survive in this market?
