fixed cost of $200,000. Should Gabriela Manufacturing insource
or outsource the item?
4. Fast Finish, Inc. (FFI) has made a technological breakthrough
in snow board finish application. FFI will apply the finish for $0.23

2. Last week a painter painted three houses in five days. This
week she painted two houses in four days. In which week was
the painter more productive?
4. A company that makes kitchen chairs wants to compare
productivity at two of its facilities. At facility #1, six workers produced
240 chairs. At facility #2, four workers produced 210 chairs
during the same time period.Which facility was more productive?
6. Aztec Furnishings makes hand-crafted furniture for sale in
its retail stores. The furniture maker has recently installed a new
assembly process, including a new sander and polisher.With this
new system, production has increased to 90 pieces of furniture
per day from the previous 60 pieces of furniture per day. The
number of defective items produced has dropped from 10 pieces
per day to 1 per day. The production facility operates strictly
eight hours per day. Evaluate the change in productivity for
Aztec using the new assembly process.
8. Med-Tech labs is a facility that provides medical tests and
evaluations for patients, ranging from analyzing blood samples
to performing magnetic resonance imaging (MRI). Average cost
to patients is $60 per patient. Labor costs average $15 per patient,
materials costs are $20 per patient, and overhead costs are
averaged at $20 per patient.

What does your finding mean?
(b) If the average lab worker spends three hours for each patient,
what is the labor productivity ratio?

Chapter 3: Problems 2, 8, 10, 12, 14, 16, 18

2. Med-First is a medical facility that offers outpatient medical
services. The facility is considering offering an additional
service, mammography screening tests, on-site. The facility
estimates the annual fixed cost of the equipment and skills necessary
for the service to be $120,000. Variable costs for each patient
processed are estimated at $35 per patient. If the clinic plans to
charge $55 for each screening test, how many patients must it
process a year in order to break even?
8. George Fine, owner of Fine Manufacturing, is considering
the introduction of a new product line. George has considered
factors such as costs of raw materials, new equipment, and requirements
of a new production process. He estimates that the
variable costs of each unit produced would be $8 and fixed costs
would be $70,000.
(a) If the selling price is set at $20 each, how many units have
to be produced and sold for Fine Manufacturing to break
even? Use both graphical and algebraic approaches.
(b) If the selling price of the product is set at $18 per unit,
Fine Manufacturing expects to sell 15,000 units. What
would be the total contribution to profit from this product
at this price?
(c) Fine Manufacturing estimates that if it offers the product
at the original target price of $20 per unit, the companywill sell about 12,000 units.Which pricing strategy—$18
per unit or $20 per unit—will yield a higher contribution
to profit?
(d) Identify additional factors that George Fine should consider
in deciding whether to produce and sell the new product.
10. Easy-Tech Software Corporation is evaluating the production
of a new software product to compete with the popular word
processing software currently available. Annual fixed costs of producing

$10 per unit. The current selling price of the item is $35 per unit,
and the annual sales volume is estimated at 50,000 units.
(a) Easy-Tech is considering adding new equipment that
would improve software quality. The negative aspect of
this new equipment would be an increase in both fixed
and variable costs. Annual fixed costs would increase by
$50,000 and variable costs by $3. However, marketing expects
the better-quality product to increase demand to
70,000 units. Should Easy-Tech purchase this new equipment
and keep the price of their product the same? Explain
your reasoning.
(b) Another option being considered by Easy-Tech is the increase
in the selling price to $40 per unit to offset the additional
equipment costs. However, this increase would
result in a decrease in demand to 40,000 units. Should
Easy-Tech increase its selling price if it purchases the new
equipment? Explain your reasoning.
12. Mop and Broom Manufacturing is evaluating whether to
produce a new type of mop. The company is considering the operations
requirements for the mop as well as the market potential.
Estimates of fixed costs per year are $40,000, and the variable
cost for each mop produced is $20.
(a) If the company sells the product at a price of $25, how
many units of product have to be sold in order to break
even? Use both the algebraic and graphical approaches.
(b) If the company sells 10,000 mops at the product price of
$25, what will be the contribution to profit?

40 patients per day. Determine process velocity and efficiency for
the clinic.

to expand again in five years.
The owners have estimated the following chances for demand:
• The likelihood of demand being high is 0.70.
• The likelihood of demand being low is 0.30.
Profits for each alternative have been estimated as follows:
• Large expansion has an estimated profitability of either
$80,000 or $50,000, depending on whether demand turns
out to be high or low.
• Small expansion has a profitability of $40,000, assuming demand
is low.
• Small expansion with an occurrence of high demand would
require considering whether to expand further. If the bakery
expands at this point, the profitability is to be $50,000.

should do.

chances for demand:
• The likelihood of demand being high is 0.70.
• The likelihood of demand being low is 0.30.
Estimated profits for each alternative are as follows:

$100,000 or $70,000, depending on whether demand turns
out to be high or low.
• Small expansion has a profitability of $50,000, assuming
that demand is low.
• Small expansion with an occurrence of high demand would
require considering whether to expand further. If the business
expands at this point, the profitability is expected to be
$90,000. If it does not expand further, the profitability is expected
to be $60,000.
