An industry currently has 100 firms, each of whichhas fixed cost of $16 and average variable cost asfollows:Quantity Average Variable Cost1 $12 23 34 45 56 6a. Compute a firm’s marginal cost and average totalcost for each quantity from 1 to 6.b. The equilibrium price is currently $10. How muchdoes each firm produce? What is the total quantitysupplied in the market?c. In the long run, firms can enter and exit themarket, and all entrants have the same costs asabove. As this market makes the transition to itslong-run equilibrium, will the price rise or fall?Will the quantity demanded rise or fall? Will thequantity supplied by each firm rise or fall? Explainyour answers.d. Graph the long-run supply curve for this market,with specific numbers on the axes as relevant.

JYour business has the capacity to produce up to 5 units/week. The table & graph below show average cost (AC) for different weekly production levels. Your objective is to maximize profit each week. Average Cost 22 20 AC 18 1 20 14 2 15 12 3 12 10 1 2 4 4 13 Quantity 15 Your product sells in the market for $21/unit, and you can sell as many units at that price as you can bring to market. You know from your economics training that deciding how much to produce should rely on marginal concepts like marginal cost (MC). So, based on the AC table above, create a table that shows the MC of each unit. (Assume that there are no fixed costs, so total costs are zero if Q=0.) Based on MC for each unit, determine the profit-maximizing quantity to produce and sell. BRIEFLY explain your answer. (Your answer needs to be based on MC and being able to sell each unit for $21.) AC ($/unit)

3. Johnny Rockabilly has just finished recording his latest CD. His record company's marketing department determines that the demand for the CD is as follows: Price Number of CDs $24 10 000 22 20 000 20 20 30 000 18 40 000 16 50 000 14 60 000 The company can produce the CD with no fixed cost and a variable cost of $5 per CD. a. Find total revenue for quantity equal to 10 000, 20 000, and so on. What is the marginal revenue for each 10 000 increase in the quantity sold? b. What quantity of CDs would maximize profit? What would be the price? What would be the profit? c. If you were Johnny's agent, what recording fee would you advise Johnny to demand from the record company? Why?

Calculate the firm's total cost for each level of production and complete the table. b) Assume that the market price of a fruit basket is €15. To maximize profit, how many fruit baskets should the firm sell? c) At the profit-maximizing quantity, what is the profit?

The market for fertilizer is perfectly competitive.Firms in the market are producing output but arecurrently incurring economic losses.a. How does the price of fertilizer compare to theaverage total cost, the average variable cost, andthe marginal cost of producing fertilizer?b. Draw two graphs, side by side, illustrating thepresent situation for the typical firm and for themarket.c. Assuming there is no change in either demand orthe firms’ cost curves, explain what will happenin the long run to the price of fertilizer, marginalcost, average total cost, the quantity supplied byeach firm, and the total quantity supplied to themarket.

Suppose that bicycles are produced by a perfectly competitive, constant-cost industryWhich of the following will have a larger effect the long-run price of bicycles: a government program to advertise the health benefits of bicyclingor (2) a government program increases the demand for steel, an input in the manufacture of bicycles that is produced in an increasing cost industry ? O. Option 1: shifts the demand curve out and increases the price. O. Option 2: shifts the supply curve up and increases the price O. Option 2: it shifts the demand curve up and increases the quantity. O. Option 2: shifts the supply curve up and increases the quantity.

2. Firm A makes and sells motor cycles. The total cost of each cycle is the sum of the costs of frames, assembly and engine. The firm produces its own engines according to the cost equation C₁=250,000 + 1,000Q +5Q² The cost of frames and assembly is $2,000 per cycle. Monthly demand for cycles is given by the inverse demand equation: P = 10,000-30Q Calculate the MC of producing an additional engine.
