Demonstration Problems for Chapter 11
Demonstration Problem 11-1
Applying Cost Behavior Concepts to Business Decisions
Art On Tour, Inc. (AOTI) contracts with artists to exhibit their work to the public. AOTI has
agreed to pay a well known artist a $20,000 commission for the right to exhibit his work for one
month.
Required
Part a – Identifying Cost Behavior
1. Determine the total commission cost and the commission cost per person if 1,000, 2,000, or
4,000 people attend the exhibition. Is the commission cost fixed or variable?
2. AOTI sells to patrons books illustrating the artist’s work. The books cost AOTI $5 each.
Determine the total cost of books and the cost per person if 1,000, 2,000, or 4,000 people attend
the exhibition and wish to purchase the books. Is the book cost fixed or variable?
Part b – Operating Leverage and Risk/Reward Relationship
1. AOTI pays an artist a $20,000 commission. It sells 4,000 tickets at $6 each. Prepare an income
statement. Then prepare revised income statements assuming 10 percent more than 4,000 and
10 percent fewer than 4,000 patrons attend the exhibition. Calculate the percentage changes
in revenue and net income if attendance increases or decreases 10 percent.
2. Alternatively, AOTI pays the artist a commission of $5 per ticket sold. It sells 4,000 tickets at
$6 each. Prepare an income statement. Then prepare revised income statements assuming 10
percent more than 4,000 and 10 percent fewer than 4,000 patrons attend the exhibition.
Calculate the percentage change in revenue and net income if attendance increases or decreases
10 percent.
Part c --Fixed and Variable Cost Definitions are Context Sensitive
1. AOTI pays the artist a commission of $20,000 per exhibition. What is the total commission
cost and the commission cost per person if 1,000, 2,000, or 4,000 people attend the exhibition?
(Same as part a.1.)
2. AOTI pays the artist a commission of $20,000 per exhibition. What is the total commission
cost and the commission cost per exhibition if AOTI sponsors 1, 2, or 3 exhibitions?
Demonstration Problem 11-2 Effect of Cost Structure
My Company / Your Company
My Company and Your Company provide rafting tours on Big Bear River. My Company pays
tour guides fixed salaries. It budgets salaries expense at $160,000 per year. Your Company pays
tour guides $40 per rafter served. Rafters are charged $50 per tour. Both companies expect to
carry approximately 4,000 rafters during the year.
Required
a. Prepare budgeted annual income statements for the two companies.
b. In an effort to lure rafters away from Your Company, My Company lowers the price per rafter
to $39. Prepare revised income statements for both companies. Assume that My Company
serves 6,000 rafters who each pay $39 per tour, while Your Company serves only 2,000 rafters
who pay $50 per tour.
c. Assume you are president of Your Company. Offer defensive strategies.
d. Suppose Your Company matches the $39 price set by My Company. Prepare income
statements for both companies assuming that each company serves 4,000 customers.
Demonstration Problem 11-3 Effect of Operating Leverage
Sharon Virgil owns a delivery service company. She charges customers $10 per delivery. The
company’s variable expenses average $2 per delivery and fixed costs are $600 per month. Ms.
Virgil provided 100 deliveries during the most recent month.
Required
a. Prepare an income statement using a contribution margin format.
b. Determine the magnitude of operating leverage. Use your answer to determine the percentage
change in net income if sales increase by 10%.
c. Assume that sales increase by 10% (deliveries increase to 110). Prepare a contribution margin
format income statement assuming 110 deliveries. Calculate the percentage change in net income
and compare your answer with your solution to part b.
Demonstration Problem 11-4 Cost-Volume-Profit Analysis
Jeff Jamail is evaluating a business opportunity to sell cookware at trade shows. Mr. Jamail can
buy the cookware at a wholesale cost of $210 per set. He plans to sell the cookware for $350 per
set. He estimates fixed costs such as plane fare, booth rental cost, and lodging to be $5,600 per
trade show.
Required
a. Determine the number of cookware sets Mr. Jamail must sell at a trade show to break even
(zero profit or loss). Use the following structure to answer this question:
(1) Contribution Margin Per Unit Approach:
a. Determine the amount of the contribution margin per unit.
b. Explain that when the total contribution margin is sufficient to pay for the fixed cost,
Mr. Jamail will break even. Show the computation of break-even in units.
c. Show how to compute the break-even point in number of dollars using the break-even
point in units and the selling price.
d. Confirm the results by preparing an income statement.
(2) Contribution Margin Ratio Approach.
a. Calculate the contribution margin ratio.
b. Use the ratio to calculate the break-even point in sales dollars, then use the results and
the selling price to calculate the break-even point in units.
(3) Equation Approach.
a. Calculate the break-even point in units.
b. Calculate the break-even point in sales dollars.
b. Assume Mr. Jamail desires to earn a profit of $4,900 per show.
(1) Determine the sales volume in units (sets of cookware) necessary to earn the desired profit.
(2) Determine the sales volume in dollars necessary to earn the desired profit.
(3) Using the contribution margin format, prepare an income statement to confirm your
answers to parts 1 and 2.
c. Determine the margin of safety between the sales volume at the break-even point and the sales
volume required to earn the desired profit. Determine the margin of safety both in sales
dollars and as a percentage.
d. After researching the market, Mr. Jamail concludes that the $350 per set selling price is too
high. Customers will likely pay only $310 per set. Mr. Jamail believes he can obtain a cost
reduction from his supplier of $20 per set (variable cost drops from $210 per set to $190 per
set) and still provide the level of quality required to achieve a sales volume of 75 sets. Under
these circumstances, what amount of fixed costs can Mr. Jamail incur and still obtain the
target profit of $4,900? Support your answer with appropriate computations.

My Company was able to increase total revenue because the decrease
in price was offset by an increase in volume. In other words, 6,000
customers paying $39 each produce more revenue ($234,000) than do
Company out of business. My Company stands to gain an additional
$78,000 ($39 x 2,000) of revenue when it takes over Your Company’s

The most common strategy students offer is to create product
differentiation. Many variations of this strategy are possible. Your
Company could use a different type of raft, travel different routes,
Students also commonly suggest cutting costs by paying the tour
guides less. Students often offer strategies involving employees
Occasionally someone suggests a merger. The merged company
could retain the salaried tour guides and dismiss those paid on a

is for Your Company to match My Company’s price and hold firm. As
