Consider the following costs of owning and operating a car. A $15,000 Fiat 500 Pop financed over 60 months at 7 percent interest means a monthly payment of $297. Insurance costs $100 a month regardless of how much you drive. The car gets 25 miles per gallon and uses regular-grade gasoline that costs $2.10 per gallon. Finally, suppose that wear and tear on the car costs about $0.10 a mile. Which costs are fixed, and which are variable? The marginal cost of driving a mile is $0.18. (Round your response to two decimal places.) I n deciding whether to drive from Atlanta to Las Vegas (about 2,000 miles round-trip) to visit a friend, which costs would you consider? Why?
Fixed costs are the monthly car payment and the cost of insurance; variable costs are the cost of gasoline and costs associated with wear and tear. Variable costs, because they will increase with each mile driven.

The short-run supply curve of a perfectly competitive firm is:
the portion of the marginal cost curve that lies above minimum average variable cost.
The optimal method of production is:
the production method that minimizes cost for a given level of output.

Economic profit can be calculated as: The normal rate of return on capital is the opportunity cost of capital.
total revenue −(explicit costs + implicit costs). True
Total cost is the total of out-of-pocket costs, the normal rate of return on capital, and opportunity costs of all factors of production.
true
The concept of economies of scale refers to lower per-unit production costs at higher levels of output. The easiest way to understand this is to look at whether long-run average cost decreases with output (economies of scale) or whether long-run average cost increases with output (diseconomies of scale). If average cost is constant as output rises, there are constant returns to scale. But the concept of falling unit costs is all around us. Explain how the concept of economies of scale helps shed light on the following: Ebooks versus printed books
B. Cost savings would include resource costs, production costs, and distribution costs for ebooks versus printed books.
In addition to gambling, Las Vegas is famous for its live production shows. Close to 100 shows are performed at various venues across the city on any given day, and many of the shows are multi-million dollar productions with months-long waiting lists for the best seats. Box office ticket prices range from less than $10 for a few of the smaller shows to over $200 for some of the major productions. In recent years, a number of these shows have begun offering tickets for sale at half price through discount ticket outlets. These half-price tickets are only available on the day of the show, on a first-come, first-served basis. Using the concept of marginal cost, explain why many of these productions have begun to offer these half-price tickets. Once a show has been scheduled and sufficient seats sold to make it profitable to stage, the marginal cost of filling remaining seats is probably near zero. Even at half-price, the added revenue will exceed the negligible marginal cost of filling the remaining seats, enabling the show's promoter to enhance its profit. Who among the following do you suppose are the most-likely customers to purchase show tickets through these discount ticket outlets? (Check all that apply.)
B. Individuals traveling with a limited entertainment budget. Your answer is correct. C. People having a flexible vacation itinerary and thus needing little certainty in their schedule. Your answer is correct. D. People who are not 'picky' about seat quality (location). Can you think of any reasons why a production show would choose to not offer tickets in this manner? (Check all that apply.) A. The shows are always sold out in advance. B. Perceptions of the show's quality may suffer. C. Ticket sales at regular prices may decline. D. All of the above are plausible. ALL OF THE ABOVE IS THE CORRECT ANSWER
Which of the following is true regarding average fixed cost?

Average variable cost (AVC) is falling.
Jessica sells carrots at a small vegetable stand in a weekly farmers' market that contains many such stands. On average, she produces and sells 150 pounds of carrots at $0.50 per pound. Her total cost of producing carrots is $75 per week. She needs to decide whether or not to increase the production of carrots. She has been told that the market for carrots demonstrates constant returns to scale. If this is the case, what is the average cost to produce each pound of carrots when she increases production to 300 pounds of carrots per week?
$0.50 per pound.

Ben Cartwright runs the Wild West Wax Museum in Carson City, Nevada. The museum has been in business for 40 years and is a major tourist attraction. The total value of the museum's capital stock is $3.5 million, which Ben owns outright. This year, the museum earned a total of $1.4 million after out-of-pocket expenses. Without taking the opportunity cost of capital into account, this means that Ben is earning a 40 percent return on his capital. Suppose that risk-free bonds are currently paying a rate of 10 percent to those who buy them. What is meant by the "opportunity cost of capital"? Explain why opportunity costs are "real" costs even though they do not necessarily involve out-of-pocket expenses.
The implicit cost of capital The capital could have instead earned a normal rate of return invested in bank certificates of deposit. The opportunity cost of Ben's capital is $350000. (Enter your response as a whole number.) Ben is earning an excess profit of $1050000. (Enter your response as a whole number.)
Which of the following is true regarding the relationship between total variable cost (TVC) and marginal cost (MC)?
The marginal cost curve is equal to the slope of the total variable cost curve.
he following are the points on a production function. Units of Labor (L) Total Output (Q) 0 0 100 15000 300 25000 Consider the graph of the marginal product as a function of labor based on the table above. Does this graph exhibit diminishing returns? Explain your answer.
The marginal product from 0 to 100 units of labor would equal 150.00 and would be drawn as a horizontal line between 0 units of labor and 100 units of labor. The marginal product from 100 to 300 units of labor would equal 50.00 and would be drawn as a horizontal line between 100 units of labor and 300 units of labor. Yes, it does exhibit diminishing returns, because the marginal product of labor decreases.
Assume a competitive market is initially in equilibrium where firms are earning a normal rate of return. Suppose there is a demand shock in this market that causes the demand curve to shift to the left, resulting in a lower market price. What adjustments would occur in the long run?
There would be an exit of firms from the market, causing the supply curve to shift to the left, raising the price until firms earn zero profit.
After working for 25 years as personal fitness trainers while raising their kids, three sisters cashed in a total of $120,000 in bonds and decided to open a small, neighborhood fitness center. They spent the $120,000 on exercise equipment, advertising, computer equipment, and other furnishings for the business. For the next 3 years, they took in $150,000 in revenue each year, paid themselves $30,000 annually each, and rented a space in a strip mall for $20,000 per year. Before the investment, their $120,000 in bonds were earning interest at a rate of 12 percent. Are they now earning economic profits? Explain your answer.
They are earning profits of $25,600, which takes into account the $14,400 opportunity cost of their capital and the $90,000 combined opportunity cost of their own labor.
[Related to the Economics in PracticeLOADING... in this section] Danny has entered a competition in which he must drive from his home town of Charlotte, North Carolina to Washington, D.C., a distance of approximately 420 miles. If he arrives in 6 hours (an average speed of 70 mph), he will receive a prize of $300. If he arrives in 7 hours (an average speed of 60 mph), he receives $280. One of the competition rules is he must pay for his own gasoline, and Danny has calculated that he will average 24 miles per gallon at 70 mph and 30 miles per gallon at 60 mph.
To maximize his winnings (prize money minus the cost of gasoline), at what speed should Danny drive if the price of gasoline is $4.00 per gallon? Danny should drive at 70miles per hour. Alternatively, if the price of gasoline is $5.00 per gallon, then Danny should drive at 70 miles per hour. At what gasoline price would Danny be indifferent to arriving in either 6 hours or 7 hours if he wants to maximize his winnings? He would be indifferent if the price was $5.71 per gallon.

As of June 2014, John Green's international bestselling novel, The Fault in Our Stars, had sold more than 10.7 million copies. In book publishing, fixed costs are high and marginal costs are low and fairly constant. Suppose that the marginal cost of the print version of The Fault in Our Stars is $1.00 per book and is the same for each book up to 20 million copies. Assume that this includes all variable costs. Explain why in this case marginal cost (MC) is a horizontal line, as is average variable cost (AVC). Marginal cost and variable cost are horizontal lines because these costs are unchanging with output. Suppose that the fixed cost of producing The Fault in Our Stars is $20 million. The average total cost (ATC) of the book if the publisher produces 5 million copies is $5. (Round your response to two decimal places.)

Indicate whether you agree or disagree with the following statements. Briefly explain your answers. Increasing returns to scale refers to a situation where an increase in a firm's scale of production leads to higher costs per unit produced. The above statement is incorrect. Increasing returns to scale refers to a situation where a firm's long-run average cost curve slopes downward. Therefore, an increase in the firm's scale of production leads to lower average costs. Constant returns to scale refers to a situation where an increase in a firm's scale of production has no effect on costs per unit produced. The above statement is correct. Decreasing returns to scale refers to a situation where an increase in a firm's scale of production leads to lower costs per unit produced. The above statement is incorrect. Decreasing returns to scale refers to a situation where a firm's long-run average cost curve slopes upward. Therefore, an increase in the firm's scale of production leads to higher average costs.
