1. A company uses a job-order costing system. Which of the following costs is
most appropriately assigned to a specific job using a predetermined overhead
rate?
A. Direct materials used in production
B. Direct labor wages paid to assembly workers
C. Depreciation on factory equipment
D. Sales commissions paid to the marketing team
Correct Answer: C. Depreciation on factory equipment
Rationale: Depreciation on factory equipment is an indirect manufacturing cost, or
manufacturing overhead, which cannot be traced directly to a specific job. A
predetermined overhead rate is used to allocate these indirect costs to jobs based
on a cost driver. Direct materials (A) and direct labor (B) are traced directly to jobs.
Sales commissions (D) are period costs, not product costs.
2. In cost-volume-profit (CVP) analysis, the contribution margin ratio is
calculated as:
A. Total fixed costs divided by the unit contribution margin.
B. Contribution margin divided by sales.
,C. Sales minus variable costs.
D. Fixed costs divided by the contribution margin ratio.
Correct Answer: B. Contribution margin divided by sales.
Rationale: The contribution margin ratio represents the percentage of each sales
dollar available to cover fixed costs and generate profit. It is calculated as total
contribution margin (sales minus variable costs) divided by total sales. Option A
calculates the break-even point in units. Option C is the definition of total
contribution margin, not the ratio. Option D is the formula for break-even sales
dollars.
3. Which of the following is a characteristic of a variable cost?
A. It remains constant in total as activity levels change.
B. It decreases per unit as activity levels increase.
C. It changes in direct proportion to changes in activity levels.
D. It is not relevant for decision-making.
Correct Answer: C. It changes in direct proportion to changes in activity levels.
Rationale: By definition, a variable cost changes in total in direct proportion to
changes in the activity level. While the total cost changes, the per-unit cost remains
constant. Option A describes a fixed cost. Option B describes the behavior of a fixed
cost on a per-unit basis. Variable costs are often highly relevant for decisions like
pricing and special orders, making D incorrect.
,4. A company’s actual manufacturing overhead costs for the period totaled
$450,000, while the applied overhead based on direct labor hours was
$480,000. This difference is referred to as:
A. Underapplied overhead.
B. Overapplied overhead.
C. A period cost variance.
D. A material variance.
Correct Answer: B. Overapplied overhead.
Rationale: When applied overhead exceeds actual overhead, the difference is
overapplied overhead. This occurs when the predetermined rate estimated more
overhead or the actual activity level was higher than expected. Underapplied
overhead (A) is the opposite—when actual overhead exceeds applied. This is a
manufacturing overhead variance, not a period cost variance (C) or a material
variance (D).
5. Which of the following statements is true regarding the contribution format
income statement?
A. It separates costs into product and period costs.
B. It is primarily prepared for external financial reporting.
C. It calculates gross margin by subtracting cost of goods sold from sales.
D. It is useful for internal decision-making and CVP analysis.
Correct Answer: D. It is useful for internal decision-making and CVP analysis.
, Rationale: The contribution format income statement separates costs by behavior
—variable and fixed—rather than by function. This structure is essential for CVP
analysis, break-even calculations, and managerial decision-making. It is not used
for external reporting (B), which requires a functional format. It calculates
contribution margin, not gross margin (C). Cost separation by product and period
(A) is a characteristic of a traditional income statement.
6. A company produces a single product. The selling price is $50 per unit,
variable costs are $30 per unit, and total fixed costs are $100,000. What is the
break-even point in units?
A. 2,000 units
B. 3,333 units
C. 5,000 units
D. 10,000 units
Correct Answer: C. 5,000 units
Rationale: The break-even point in units is calculated as fixed costs divided by the
unit contribution margin. The unit contribution margin is $50 - $30 = $20.
Therefore, the break-even point is $100,000 / $20 = 5,000 units. Option A (2,000
units) uses an incorrect contribution margin of $50. Option B (3,333 units)
incorrectly uses a contribution margin of $30. Option D (10,000 units) uses a
contribution margin of $10.
7. In a process costing system, equivalent units of production are used to:
