Use the following table to work Problems 17 to 20. The table shows the production function of Jackie's Canoe Rides. Labor Output (rides per day) (workers per day) Plant 1 Plant 2 Plant 3 Plant 4 10 20 40 55 65 20 40 60 75 85 30 65 75 90 100 40 75 85 100 110 Canoes 10 20 30 40 Jackie's pays $100 a day for each canoe it rents and $50 a day for each canoe operator it hires. 19. a. On Jackie's LRAC curve, what is the average cost of producing 40, 75, and 85 rides a week? b. What is Jackie's minimum efficient scale?

How does fixed cost affect marginal cost? Why is this relationship important?

Continuing from Exercise 7.1, the films factory sits on land owned by the firm that it could rent for 30,000 per year. What was the films economic profit last year?

Are there fixed costs in the lung-run? Explain briefly.

Are fixed costs also sunk costs? Explain.

When the first automobiles were built in 1901, they were made by skilled workers using hand tools. Later, in 1913, Henry Ford introduced the moving assembly line, which lowered costs and speeded production. Over the years, the production line has become ever more mechanized, and today robots replace people in many tasks. Search The graph below shows the demand curve for cars in 1901. Suppose the least-possible cost of producing a car is $250 and that the efficient scale is 0.5 cars a day. D Draw the average total cost curve in 1901. Label it ATC₁ 500- 400- Price (dollars per car) 300- Q SON The graph below shows the demand curve for cars in 2020. Suppose the least possible cost of producing a car is $10,000 and that the efficient scale is 200,000 cars a day Draw the average total cost curve in 2020 Label it ATC₂ Price (dollars per car) 50,000 40,000 30,000+ Next Q

It only the productivity of the truck Adam chooses to rent decreases, which of the following would be true at the new profit maximizing level of output and length of truck? Select the two that apply O A decrease in marginal cost O A decrease in total costs O A decrease in total revenuo O An incroase in the amount of labor Adam hires Revenue

The marginal or additional gain from Kyoko second hr of work from 9am to 10am is what problems?

Production costs of books are presented in the table below. Labor Quantity Fixed Cost Variable Cost Total Cost MarginalCost AverageTotal Cost 0 0 $80 $0 $80     1 10 $80 $30 $110     2 26 $80 $60 $140     3 46 $80 $90 $170     4 65 $80 $120 $200     5 78 $80 $150 $230     Using the table above, find out the marginal cost of the 46th book produced, in dollars.

Typed plz and asap thanks
