correct, 16.3-15 The graph shows the demand, marginal revenue, and marginal cost curves for a a monopoly producer. The horizontal axis measures the quantity in pounds of steaks per hour, from 0 to 5,000, increasing by 1,000. The vertical axis measures the price and cost in dollars per pound of steak, from 0 to $20.00, increasing by $2.00. The graph shows an upward-sloping, convex curve, labeled S=MC, and two downward-sloping, linear curves, labeled MR and D, starting at the same point on the vertical axis, at a price of $20. The MR curve lies below the D curve. The S=MC curve intersects the D curve at a point corresponding to a quantity of 3,000 and a price of $8. The S=MC curve intersects the MR curve at a point corresponding to a quantity of 2,000 and a cost of $4. The combinations of quantity and price along the D curve are (0, 20), (1,000, 16), (2,000, 12), (3,000, 8), and (4,000, 4). Suppose the grocery store market in Kansas City is perfectly competitive. Then one store buys all the others and becomes a singleminus price monopoly. The figure above shows the relevant demand and cost curves. When the market is a monopoly, the price of a pound of steak is
