11. LO.
1 (Association with cost object) Following is a list of raw materials that might be used in the production of a laptop
computer: touch pad and buttons, glue, network connector, battery, paper towels used by line employees, AC adapter, CD
drive, motherboard, screws, and oil for production machinery. The laptops are produced in the same building and using the
same equipment that produces desktop computers and servers. Classify each raw material as direct or indirect when the cost
object is the
a. laptop.
b. computer production plant.
(a) When the Cost Object is the Laptop
Direct Materials (DM) – Costs that can be directly (easily/economically) traced to the production of a laptop.
Can readily see material in the laptop
Indirect Materials (IM) – Costs that are necessary for production but cannot be directly traced to a single
laptop unit.

***All these costs are conveniently, easily, and economically directly attributable/ traceable to the plant. Cannot
be costed to another manufacturing plant
SUMMARY OF KEY DIFFERENCES
   For laptops → Materials directly used in making the laptop are direct, while those used in production but not
traceable to each unit are indirect.
  For the production plant → Anything related to the general facility and equipment maintenance is direct,
while product-specific materials become indirect because they do not benefit the entire plant.
12. LO.1 (Association with cost object) Morris & Assoc., owned by Cindy Morris, provides accounting services to clients. The
firm has two accountants (Jo Perkins who performs basic accounting services and Steve Tompkin who performs tax
services) and one office assistant. The assistant is paid on an hourly basis for the actual hours worked. One client the firm
served during April was Vic Kennedy. During April 2010, the following labor time was incurred. Classify the labor time as
direct or indirect based on whether the cost object is (1) Kennedy’s services, (2) tax services provided, or (3) the accounting
firm.
a. Four hours of Perkins’s time in preparing Kennedy’s financial statements
b. Six hours of the assistant’s time in copying Kennedy’s tax materials
c. Three hours of Morris’s time playing golf with Kennedy
d. Eight hours of continuing education paid for by the firm for Tompkin to attend a tax update seminar
e. One hour of the assistant’s time spent at lunch on the day that Kennedy’s tax return was prepared
f. Two hours of Perkins’s time spent with Kennedy and his banker discussing Kennedy’s financial statements
g. One-half hour of Tompkin’s time spent talking to an IRS agent about a deduction taken on Kennedy’s tax return
h. Forty hours of janitorial wages

KEY TAKEAWAYS
   Direct costs → Easily traceable to the cost object (client services or tax services).
   Indirect costs → Related to firm-wide operations, not a specific client or service.
  For the accounting firm as a cost object, expenses like janitorial wages and continuing education are direct
because they support the overall firm operations.
19. LO.2 & LO.3 (Cost behavior and classification) Indicate whether each of the following items is a variable (V), fixed (F), or
mixed (M) cost and whether it is a product/service (PT) or period (PD) cost. If some items have alternative answers, indicate
the alternatives and the reasons for them.
a. Wages of factory maintenance workers
b. Wages of forklift operators who move finished goods from a central warehouse to the outbound loading dock
c. Insurance premiums paid on the headquarters of a manufacturing company
d. Cost of labels attached to shirts made by a company
e. Property taxes on a manufacturing plant
f. Paper towels used in factory restrooms

KEY TAKEAWAYS
   Manufacturing (Mfg.) → Has factory-related costs (e.g., factory depreciation, finished goods inventory,
direct labor wages).
  Merchandising (Mer.) → Focuses on buying and selling inventory (e.g., merchandise inventory, COGS).
  Service (Ser.) → Primarily sells services, so terms like "cost of services rendered" apply.
41. LO.2 (Cost behavior) Mason Company’s cost structure contains a number of diff erent cost behavior patterns. Following
are descriptions of several different costs; match these to the appropriate graphs. On each graph, the vertical axis represents
cost and the horizontal axis represents level of activity or volume. Identify, by letter, the graph that illustrates each of the
following cost behavior patterns. Each graph can be used more than once.
1. Cost of raw material, where the cost decreases by $0.06 per unit for each of the first 150 units purchased,
after which it remains constant at $2.75 per unit.
2. City water bill, which is computed as follows: first 750,000 gallons or less, $1,000 flat fee; next 15,000
gallons, $0.002 per gallon used; next 15,000 gallons, $0.005 per gallon used; next 15,000 gallons, $0.008 per
gallon used; and so on.
3. Salaries of maintenance workers, assuming one maintenance worker is needed for every 1,000 hours or
less of machine time.
4. Electricity rate structure—a flat fixed charge of $250 plus a variable cost after 150,000 kilowatt hours are
used.
5. Depreciation of equipment using the straight-line method.
6. Rent on a machine that is billed at $1,000 for up to 500 hours of machine time. After 500 hours of machine
time, an additional charge of $1 per hour is paid up to a maximum charge of $2,500 per period.
7. Rent on a factory building donated by the county; the agreement provides for a monthly rental of $100,000
less $1 for each labor hour worked in excess of 200,000 hours. However, a minimum rental payment of
$20,000 must be made each month. 8. Cost of raw material used.
9. Rent on a factory building donated by the city with an agreement providing for a fixed-fee payment unless
250,000 labor hours are worked, in which case no rent needs to be paid.

decreasing per-unit cost until 150                                          initially decreases at a diminishing
      units, then constant                                                  rate and then flattens out.)

with one worker per 1,000 hours                                               as new workers are hired after
