Figure 7.4a: Cheerios Price-Quantity Diagram with Demand and Isoprofit Curves
This price-quantity diagram for Cheerios plots quantity in pounds (0 to 80,000) on the horizontal axis against price per pound ($0 to $10) on the vertical axis. It features a downward-sloping, convex demand curve that runs between the points (0, $7) and (80,000, $1). The diagram also displays several non-intersecting, downward-sloping, convex isoprofit curves. The $60,000 curve is positioned above the demand curve, the $34,000 curve is tangent to it, and the $10,000 curve intersects it at two points. A horizontal line at $2 per pound represents the zero-profit isoprofit curve, which is located below the other curves.

Why Profit Maximization Implies Price Exceeds Marginal Cost
A company with a downward-sloping demand curve is analyzing its pricing and output strategy. It has identified four key scenarios, where each 'isoprofit curve' represents all price-quantity combinations that yield a specific, constant level of profit. Higher isoprofit curves represent higher profit levels.
- Scenario A: A price-quantity combination on a very high isoprofit curve, but this combination is not on the demand curve.
- Scenario B: A price-quantity combination that lies on the demand curve and also on an isoprofit curve that intersects the demand curve at two different points.
- Scenario C: A price-quantity combination that lies on the demand curve and is the single point of tangency with the highest possible isoprofit curve the firm can reach.
- Scenario D: A price-quantity combination that lies on the demand curve and also on the isoprofit curve representing zero profit.
Which scenario describes the firm's profit-maximizing choice?
Evaluating a Firm's Pricing Strategy
True or False: For a firm with a downward-sloping demand curve, if a specific price-quantity combination lies at a point where an isoprofit curve crosses the demand curve, it is always possible for the firm to increase its profit by selecting a different price and quantity combination on the demand curve.
Analyzing a Firm's Profit Position
A firm's pricing options are illustrated in the diagram described below. The solid line is the demand curve, representing all feasible price-quantity combinations. The dashed lines are isoprofit curves, with curves further from the origin representing higher profit levels. Match each labeled point (A, B, C, D) to its correct economic description.
The Rationale for Tangency in Profit Maximization
A firm is operating at a specific price-quantity combination on its downward-sloping demand curve. At this point, to maintain its current profit level, the firm's managers calculate they would be willing to decrease the price by $5 for each additional unit sold. However, they observe from the demand curve that they only need to decrease the price by $3 to actually sell one more unit. To increase the firm's profit, what should they do?
Analyzing a Suboptimal Profit Position
Optimizing Pricing for a Software Application
A firm that produces a differentiated product is operating at a point on its downward-sloping demand curve. At its current price and quantity, the managers determine that the slope of the isoprofit curve is -3. They also observe that the slope of the demand curve at this same point is -5. Based on this information, which of the following statements is correct?
