Marginal Profit (MR - MC)

Algebraic Derivation of the Marginal Revenue Formula

A company sells a product and faces an inverse demand function of P = 120 - 2Q, where P is the price per unit and Q is the quantity of units sold. What is the additional revenue generated by increasing sales from 20 units to 21 units?

Interpreting Changes in Total Revenue

Evaluating a Pricing Strategy

A firm observes that its total revenue is maximized when it sells 500 units of its product. What can be concluded about the marginal revenue for the 500th unit sold?

A company observes that after lowering the price of its product, its total revenue increased. Based on this information, it is correct to conclude that the marginal revenue associated with the additional units sold was negative.

Calculating Marginal Revenue from a Demand Schedule

A company finds that to sell a greater quantity of its product, it must lower the price for every unit it sells. Given this situation, which statement correctly compares the price of the product to the additional revenue gained from selling one more unit?

Deriving the Marginal Revenue Function

A firm faces the demand schedule provided below. Match each change in quantity sold with the corresponding marginal revenue generated by that change.

Marginal Cost as the Derivative of the Total Cost Function

A firm's total cost to produce a quantity (Q) of a good is given by the function C(Q) = 100 + 5Q + 2Q². What is the marginal cost of production when the firm is producing 10 units?

Analyzing Production Costs

A firm's total cost (TC) of production changes as the quantity (Q) of output changes. The marginal cost (MC) represents the slope, or rate of change, of the total cost curve. Below are descriptions of four different total cost curves. Match each total cost curve to the description of the marginal cost curve it implies.

Marginal vs. Average Cost Decision-Making

A company observes that its total cost to produce 10 widgets is $500. When it increases production to 11 widgets, its total cost rises to $540. Based on this information, the marginal cost of producing the 11th widget is equal to the average total cost of producing 11 widgets.

Relationship Between Total Cost and Marginal Cost

A company's total cost to produce 200 units of a product is $5,000. When it increases production to 201 units, its total cost rises to $5,025. Based on this information, the marginal cost of producing the 201st unit is $____.

A firm's production schedule shows the total cost associated with different levels of output. Based on the data provided in the table below, arrange the following production intervals in ascending order (from lowest to highest) of their marginal cost.

A company manufactures widgets and sells them for a constant price of $15 each. The company is currently producing 1,000 widgets per week. At this level of production, the firm calculates that the additional cost to produce one more widget (the 1,001st) would be $12. Assuming the company's goal is to maximize its profit, what is the most logical immediate action for the firm to take based only on this information?

The graph of a firm's total cost (TC) as a function of output quantity (Q) is shown. A tangent line drawn to the curve at an output level of Q1 is visibly less steep than a tangent line drawn to the curve at a higher output level of Q2. Based on this graphical information, what can be concluded about the firm's marginal cost (MC) at these two points?

A company's total cost (C) to produce a quantity (Q) of a product is described by the function C(Q) = 200 + 10Q + 0.25Q². What is the additional cost the company will incur to produce the 21st unit?

Analyzing Cost Behavior

Analyzing the Shape of Cost Curves

Consider a firm's total cost curve plotted on a graph, with total cost on the vertical axis and quantity of output on the horizontal axis. The curve starts at a positive cost value on the vertical axis, initially rises at a decreasing rate (becoming flatter), and then begins to rise at an increasing rate (becoming steeper). This creates a curve with a distinct inflection point. At which point on this curve would the firm's marginal cost be at its minimum?

Production Decision Analysis

A manufacturing firm observes that for every additional unit it produces, the cost to produce that specific unit remains constant. Which of the following statements best describes the firm's total cost curve when plotted with cost on the vertical axis and quantity on the horizontal axis?

A firm is currently producing at a level of output where the cost of producing one more unit is greater than the average total cost per unit. If this firm decides to increase its production by one unit, what will be the effect on its average total cost?

A firm's total cost (C) of producing a quantity of output (Q) can be represented by a mathematical function. The shape of this function determines the behavior of the additional cost incurred for each new unit produced. Match each total cost function below with the description of its corresponding marginal cost behavior.

If a firm's total cost of production is increasing as it produces more output, its marginal cost must also be increasing.

A company that manufactures high-end headphones determines the relationship between the price it sets and the quantity it can sell. It finds that to sell exactly 2,000 pairs of headphones per month, the highest price it can charge is $300 per pair. Based on this information, which of the following monthly strategies represents a price-quantity combination that is achievable for the company but would be logically inconsistent with the goal of maximizing profit?

Firm's Pricing Strategy and the Feasible Frontier

Evaluating a Firm's Pricing Proposal

A firm aiming to maximize its profit is indifferent between choosing a price-quantity combination that lies on its demand curve and one that lies directly below it, as both combinations are considered achievable.

A firm faces a downward-sloping demand curve for its product. Match each type of price-quantity combination with its correct description in the context of the firm's feasible set and profit-maximizing behavior.

Analysis of a Sub-Optimal Pricing Strategy

For a firm with market power, the demand curve represents the boundary of all achievable price and quantity combinations. Therefore, this curve is also known as the firm's ____ frontier.

Evaluating Strategic Pricing Options

A firm is analyzing its pricing strategy. The firm's demand curve represents the boundary of all achievable price and quantity combinations. The firm considers three distinct price-quantity points:

• Point A: Lies above the demand curve.
• Point B: Lies below the demand curve.
• Point C: Lies on the demand curve.

Assuming the firm's objective is to maximize profit, which statement provides the most accurate analysis of these points?

A pharmaceutical company holds a patent that makes it the sole producer of a specific brand-name allergy medication. However, several other companies sell generic versions of the same medication, which are chemically identical and considered perfect alternatives by consumers. Based on this situation, the pharmaceutical company with the patent operates in a monopoly market for allergy medication.

A firm is considered a monopoly if it is the sole seller of its product and if its product has no close substitutes. Based on this definition, which of the following scenarios best illustrates a monopoly?

Evaluating Market Structures

Match each market scenario with the description that best characterizes it.

A company is the sole producer of a new, patented smart-home device that automatically manages a home's lighting and temperature to save energy. While no other company can produce this specific device, consumers can still achieve similar energy savings by using programmable thermostats and smart light bulbs from various other manufacturers. Why would this company likely not be considered a pure monopolist from an economic perspective?
