K Find the interest rate needed for the sinking fund to reach the required amount. Assume that the compounding period is the same as the payment period. $14,129 to be accumulated in 3 years; quarterly payments of $1075. The interest rate needed is approximately %. (Type an integer or decimal rounded to two decimal places as needed.) ***

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

Check for Updates Consider a monopolist that produces coal for energy, with demand curve defined by P = 190 – 20 and marginal cost given by MC = 10 + 2Q. Also, the firm's average total cost is ATC = 100/Q + Q+ 10. (Price and costs are in dollars per tonne of coal, while quantity is in thousands of tonnes.) Calculate the monopolisť's profit-maximizing quantity, price, and profit. For a monopoly, profit maximization occurs where the marginal revenue equals the marginal cost. a. b. What would be the competitive output and price if this monopolist operated as a competitive firm?…
