DECISION MAKING SUPPLEMENT A 45 Break-Even Analysis 1. Mary Williams, owner of Williams Products, is evalu- ating whether to introduce a new product line. After thinking through the production process and the costs of raw materials and new equipment, Williams estimates the variable costs of each unit produced and sold at $6 and the fixed costs per year at $60,000. into the atmosphere. Two processes have been identi- fied that provide the same level of particulate reduc- tion. The first process is expected to incur $350,000 of fixed cost and add $50 of variable cost to each casting Spartan produces. The second process has fixed costs of $150,000 and adds $90 of variable cost per casting. a. If the selling price is set at $18 each, how many units must be produced and sold for Williams to break even? Use both graphic and algebraic approaches to get your answer. a. What is the break-even quantity beyond which the first process is more attractive? b. What is the difference in total cost if the quantity produced is 10,000? 6. A news clipping service is considering moderniza- tion. Rather than manually clipping and photocopy- ing articles of interest and mailing them to its clients, employees electronically input stories from most widely circulated publications into a database. Each new issue is searched for key words, such as a client's company name, competitors' names, type of business, and the company's products, services, and officers. When matches occur, affected clients are instantly notified via an online network. If the story is of interest, it is electronically transmitted, so the client often has the story and can prepare comments for follow-up inter- views before the publication hits the street. The manual process has fixed costs of $400,000 per year and variable costs of $6.20 per clipping mailed. The price charged the client is $8.00 per clipping. The computerized process has fixed costs of $1,300,000 per year and variable costs of $2.25 per story electronically transmitted to the client. b. Williams forecasts sales of 10,000 units for the first year if the selling price is set at $14 each. What would be the total contribution to profits from this new product during the first year? c. If the selling price is set at $12.50, Williams forecasts that first-year sales would increase to 15,000 units. Which pricing strategy ($14.00 or $12.50) would result in the greater total contribution to profits? d. What other considerations would be crucial to the final decision about making and marketing the new product? 2. A product at the Jennings Company enjoyed reasonable sales volumes, but its contributions to profits were dis- appointing. Last year, 17,500 units were produced and sold. The selling price is $22 per unit, the variable cost is $18 per unit, and the fixed cost is $80,000. a. What is the break-even quantity for this product? Use both graphic and algebraic approaches to get your answer. b. If sales were not expected to increase, by how much would Jennings have to reduce their variable cost to break even? a. If the same price is charged for either process, what is the annual volume beyond which the automated process is more attractive? c. Jennings believes that a $1 reduction in price will increase sales by 50 percent. Is this enough for Jennings to break even? If not, by how much would sales have to increase? b. The present volume of business is 225,000 per year. Many of the clippings sent with the current process are not of interest to the client or are mul- tiple copies of the same story appearing in several publications. The news clipping service believes that by improving service and by lowering the price to $4.00 per story, modernization will increase volume to 900,000 stories transmitted per year. Should the clipping service modernize? c. If the forecasted increase in business is too optimistic, at what volume will the new process (with the $4.00 price) break even? 7. Hahn Manufacturing purchases a key component of one of its products from a local supplier. The current purchase price is $1,500 per unit. Efforts to standardize parts suc- ceeded to the point that this same component can now be used in five different products. Annual component usage should increase from 150 to 750 units. Management won- ders whether it is time to make the component in-house rather than to continue buying it from the supplier. Fixed costs would increase by about $40,000 per year for the new equipment and tooling needed. The cost of raw mate- rials and variable overhead would be about $1,100 per unit, and labor costs would be $300 per unit produced. ippings d. Jennings is considering ways to either stimulate sales volume or decrease variable cost. Management believes that either sales can be increased by 30 percent or that variable cost can be reduced to 85 percent of its cur- rent level. Which alternative leads to higher contribu- tions to profits, assuming that each is equally costly to implement? (Hint: Calculate profits for both alterna- tives and identify the one having the greatest profits.) e. What is the percent change in the per-unit profit contribution generated by each alternative in part (d)? 3. An interactive television service that costs $10 per month to provide can be sold on the information highway for $15 per client per month. If a service area includes a potential of 15,000 customers, what is the most a company could spend on annual fixed costs to acquire and maintain the equipment? 4. A restaurant is considering adding fresh brook trout to its menu. Customers would have the choice of catching their own trout from a simulated mountain stream or simply asking the waiter to net the trout for them. Operating the stream would require $10,600 in fixed costs per year. Variable costs are estimated to be $6.70 per trout. The firm wants to break even if 800 trout dinners are sold per year. What should be the price of the new item? a. Should Hahn make rather than buy? b. What is the break-even quantity? c. What other considerations might be important? 8.

That forecast calls for Tri-County customers to consume 1 million MWh of energy next year. a. Techno can substantially improve the item's quality by installing new equipment at additional annual fixed costs of $60,000. Variable costs per unit would increase by $1, but, as more of the better-quality product could be sold, the annual volume would increase to 50,000 units. Should Techno buy the new equipment and maintain the current price of the item? Why or why not? a. How much will Tri-County need to charge its customers per MWh to break even next year? b. The Tri-County customers balk at that price and conserve electrical energy. Only 95 percent of fore- casted demand materializes. What is the resulting surplus or loss for this nonprofit organization? b. Alternatively, Techno could increase the selling price to $11 per unit. However, the annual sales volume would be limited to 45,000 units. Should Techno buy the new equipment and raise the price of the item? Why or why not? 10. Earthquake, drought, fire, economic famine, flood, and a pestilence of TV court reporters have caused an exodus from the City of Angels to Boulder, Colorado. The sud- den increase in demand is straining the capacity of Boul- der's electrical system. Boulder's alternatives have been reduced to buying 150,000 MWh of electric power from Tri-County G&T at a price of $75 per MWh, or refurbish- ing and recommissioning the abandoned Pearl Street Power Station in downtown Boulder. Fixed costs of that project are $10 million per year, and variable costs would be $35 per MWh. Should Boulder build or buy? 9. The Tri-County Generation and Transmission Associa- tion is a nonprofit cooperative organization that pro- vides electrical service to rural customers. Based on a faulty long-range demand forecast, Tri-County overbuilt its generation and distribution system. Tri-County now has much more capacity than it needs to serve its cus- tomers. Fixed costs, mostly debt service on investment in plant and equipment, are $82.5 million per year. Variable costs, mostly fossil fuel costs, are $25 per megawatt-hour (MWh, or million watts of power used for 1 hour). The new person in charge of demand fore- casting prepared a short-range forecast for use in next 11. Tri-County G&T sells 150,000 MWh per year of electrical power to Boulder at $75 per MWh, has fixed costs of $82.5 million per year, and has variable costs of $25 per MWh. If Tri-County has 1,000,000 MWh of demand from its customers (other than Boulder), what will Tri-County have to charge to break even? Preference Matrix 12.

fixed cost and add $50 of variable cost to each casting
Spartan produces. The second process has fixed costs of
$150,000 and adds $90 of variable cost per casting.
a. If the selling price is set at $18 each, how many units
must be produced and sold for Williams to break
even? Use both graphic and algebraic approaches to
get your answer.
a. What is the break-even quantity beyond which the
first process is more attractive?
b. What is the difference in total cost if the quantity
produced is 10,000?
6. A news clipping service is considering moderniza-
tion. Rather than manually clipping and photocopy-

matches occur, affected clients are instantly notified
via an online network. If the story is of interest, it is
electronically transmitted, so the client often has the
story and can prepare comments for follow-up inter-
views before the publication hits the street. The manual
process has fixed costs of $400,000 per year and variable
costs of $6.20 per clipping mailed. The price charged the
client is $8.00 per clipping. The computerized process
has fixed costs of $1,300,000 per year and variable costs
of $2.25 per story electronically transmitted to the client.
b. Williams forecasts sales of 10,000 units for the first
year if the selling price is set at $14 each. What
would be the total contribution to profits from this
new product during the first year?
c. If the selling price is set at $12.50, Williams forecasts
that first-year sales would increase to 15,000 units.
Which pricing strategy ($14.00 or $12.50) would
result in the greater total contribution to profits?
d. What other considerations would be crucial to the final
decision about making and marketing the new product?

is $18 per unit, and the fixed cost is $80,000.
a. What is the break-even quantity for this product? Use
both graphic and algebraic approaches to get your answer.
b. If sales were not expected to increase, by how much
would Jennings have to reduce their variable cost to
break even?
a. If the same price is charged for either process, what
is the annual volume beyond which the automated
process is more attractive?
c. Jennings believes that a $1 reduction in price will
increase sales by 50 percent. Is this enough for
Jennings to break even? If not, by how much would
sales have to increase?
b. The present volume of business is 225,000
per year. Many of the clippings sent with the current
process are not of interest to the client or are mul-
tiple copies of the same story appearing in several
publications. The news clipping service believes that
by improving service and by lowering the price to
$4.00 per story, modernization will increase volume
to 900,000 stories transmitted per year. Should the
clipping service modernize?
c. If the forecasted increase in business is too optimistic,
at what volume will the new process (with the $4.00
price) break even?
7. Hahn Manufacturing purchases a key component of one
of its products from a local supplier. The current purchase
