Assume that the market for shirts is a competitive market, and the market price is $20per shirt.The following graph shows Kenji'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 Kenji produces.200175Total Revenue150Total Cost125Profit100-2512.TOTAL COST AND REVENUE (Dollars) (circie symboI) to plot marginal revenue and the orange points (square symbol) to piot marginal cost at each quantity.4035Marginal RevenueMarginal Cost234678QUANTITY (Shirts)Kenji's profit is maximized when he producesshirts. When he does this, the marginal cost of the last shirt he produces is $which isthan the price Kenji receives for each shirt he sells. The marginal cost of producing an additional shirt (that is, one more shirt thanwould maximize his profit) is $, which isthan the price Kenji receives for each shirt he sells. Therefore, Kenji's profit-maximizingquantity corresponds to the intersection of thecurves. Because Kenji is a price taker, this last conditioncan also be written asCOSTS AND REVENUE (Dollars per shirt)

Profits are the excess of revenue receipts over the costs incurred by the firm. When the marginal…

4. Total cost, average cost, and marginal cost in the short run Suppose Kenji runs a small business that manufactures frying pans. Assume that the market for frying pans is a price-taker market, and the market price is $20 per frying pan. The following graph shows Kenji's total cost curve. Use the blue points (circle symbol) to plot total revenue, and the green points (triangle symbol) to plot profit for the first seven frying pans that Kenji produces, including zero frying pans.

2. a) George's hair-cutting business is a profit-maximizing, perfectly competitive firm. George provides haircuts at €27 each. His total cost each day is €280, of which €30 is a fixed cost. He cuts hair for 10 customers a day. What can you say about George's short-run decision regarding shutdown and his long-run decision regarding exit? (Explain using less than 100 words).
Assume that the most efficient production technology available for making vitamin pills has the cost structure given in the following table. Note that output is measured as the number of bottles of vitamins produced per day and that costs include a normal profit. Output TC MC ATC 50,800 $170,000 $0.60 100,800 220,000 1.10 150,800 257,500 1.71 200,800 365,500 2.45 Instructions: Enter your answers rounded to two decimal places. a. What is ATC per unit for each level of output listed in the table? Enter your answers in the table above. b. Are there economies of scale in production? Yes c. Suppose that the market price for a bottle of vitamins is $1.71. At that price the total market quantity demanded is 301,600,000 bottles. How many firms will be in this industry? firm(s) d. Suppose that, instead, the market quantity demanded at a price of $1.71 is only 150,800. How many firms will be in this industry? firm(s) e. Review your answers to parts b, c, and d. Does the level of demand determine…
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…

3. The components of marginal revenue Asim's HookNLadder is the only company selling fire engines in the fictional country of Alexandrina. Asim initially produced seven trucks, but then decided to increase production to eight trucks. The following graph gives the demand curve faced by Asim's HookNLadder. As the graph shows, in order to sell the additional fire truck, Asim must lower the price from $100,000 to $50,000 per truck. Notice that Asim gains revenue from the sale of the additional engine, but at the same time, he loses revenue from the initial seven engines because they are all sold at the lower price. Use the purple rectangle (diamond symbols) to shade the area representing the revenue lost from the initial seven engines by selling at $50,000 rather than $100,000. Then use the green rectangle (triangle symbols) to shade the area representing the revenue gained from selling an additional engine at $50,000. PRICE (Thousands of dollars per fire engine) 275 250 Asim 225 200 175…
