Refers to Figure 18-1. Suppose the firm sells its output for $15 per unit, and it pays each of its workers $750 per week. When output increases from 210 units to 285 units, the  a. marginal cost is $10 per unit of output. b. marginal revenue is $5 per unit of output. c. value of the marginal product of labor is $4,275. d. firm's profit decreases. Please explain why the answer is a.

Brody's firm produces trumpets in a perfectly competitive market. The table below shows Brody's total variable cost. He has a fixed cost of $240, and the price per trumpet is $60.-Calculate the average total cost of producing 6 trumpets. Show your work. -Calculate the marginal cost of producing the 11th trumpet. -What is Brody's profit-maximizing quantity? Use marginal analysis to explain your answer. -At the profit-maximizing quantity you determined in part (c), calculate Brody's profit or loss. Show your work. -Brody also produces saxophones at a loss in a perfectly competitive market. Draw a correctly labeled graph for Brody's firm showing the following at a market price of $200. -Brody's profit-maximizing quantity of saxophones -Brody's loss, completely shaded   Quantity Total Variable cost 6 $120 7 $145 8 $165 9 $220 10 $290 11 $390

Suppose fixed costs are $10,000, variable costs are $40,000 and the price of the good is $10 and quantity of the good the firm sells is $10,000.  A. Caluclate Total Costs.  B. Caluclate Total Revenue.  C. Calculate the Firm's Profits.

Answer question 6D only

Use this table to answer the following question. Output Total Variable Cost $1 $20 $2 $24 $3 $33 $4 $40 $5 $45 $6 $60 $7 $77 $8 $96 $9 $180 $10 $200 The government just mandated that all firms must install new technology to reduce pollution. The new technology costs $13. The market price is $8. In the long run, will the firm stay open or shut down?

2. A competitive firm uses two variable factors to produce its output, with a production function q min{x₁, x₂}. The price of factor 1 is $8 and the price of factor 2 is $5. Due to a lack of warehouse space, the company cannot use more than 10 units of x₁. The firm must pay a fixed cost of $80 if it produces any positive amount but doesn't have to pay this cost if it produces no butput. What is the smallest integer price that would make a firm willing to produce a positive amount? b. d. $44 $41 $29 $13 $21
