Question 1

1. $7,800
2. $10,500 (correct answer)
3. $9,300
4. $11,700

Explanation: Direct labor cost = 180 hours x $20 =$3,600. Applied overhead = 180 hours x $15 =$2,700. Total job cost = $4,200 +$3,600 + $2,700 =$10,500. Option A omits applied overhead entirely. Option C applies only part of the overhead. Option D applies an overhead rate higher than the predetermined rate.

Question 2

1. $24.00 per DLH
2. $18.00 per DLH
3. $15.00 per DLH (correct answer)
4. $12.00 per DLH

Explanation: Predetermined overhead rate = Budgeted overhead / Budgeted activity = $360,000 / 24,000 =$15.00 per DLH. Option A divides by 15,000 hours. Option B divides by 20,000 hours. Option D divides by 30,000 hours.

Question 3

1. $15,000 overapplied
2. $30,000 underapplied
3. $30,000 overapplied
4. $15,000 underapplied (correct answer)

Explanation: Applied overhead = 22,000 DLH x $15 =$330,000. Under/overapplied = Actual - Applied = $345,000 -$330,000 = $15,000 underapplied. Actual overhead exceeded applied overhead, so overhead was underapplied. Option A has the correct amount but incorrect direction. Option B uses incorrect applied overhead in the calculation. Option C has both an incorrect amount and incorrect direction.

Question 4

1. $623,000 (correct answer)
2. $685,000
3. $578,000
4. $640,000

Explanation: Cost of goods manufactured = Beginning WIP + Direct materials + Direct labor + Overhead applied - Ending WIP = $45,000 +$280,000 + $195,000 +$165,000 - $62,000 =$623,000. Option B omits the deduction for ending WIP. Option C omits beginning WIP from the calculation. Option D applies an incorrect ending WIP balance.

Question 5

1. $12.00
2. $15.50
3. $16.00
4. $14.00 (correct answer)

Explanation: Cost per equivalent unit = Total conversion costs / EUP = $280,000 / 20,000 =$14.00. Option A divides by an incorrect equivalent unit count of approximately 23,333. Option B and Option C result from arithmetic errors using incorrect denominators.

Question 6

1. $18.00 (correct answer)
2. $16.00
3. $20.00
4. $22.00

Explanation: EUP for materials = 18,000 + (4,000 x 100%) = 22,000. Cost per EU for materials = $396,000 / 22,000 =$18.00. Option B divides by 24,750, overstating equivalent units. Option C divides by 19,800. Option D divides by 18,000, treating ending WIP as having zero material content.

Question 7

1. $252,000
2. $576,000 (correct answer)
3. $504,000
4. $630,000

Explanation: Cost per completed unit = $18.00 +$14.00 = $32.00. Total cost transferred = 18,000 x$32.00 = $576,000. Option A applies only the conversion cost rate to all 18,000 units. Option C applies only the materials rate to all units. Option D applies an incorrectly higher combined rate.

Question 8

1. $128,000
2. $72,000
3. $100,000 (correct answer)
4. $56,000

Explanation: Materials cost in ending WIP = 4,000 x 100% x $18.00 =$72,000. Conversion cost in ending WIP = 4,000 x 50% x $14.00 =$28,000. Total ending WIP cost = $72,000 +$28,000 = $100,000. Option A treats ending WIP as 100% complete for conversion as well. Option B includes only the materials component. Option D includes only the conversion component.

Question 9

1. $16,700
2. $17,560
3. $19,580
4. $18,140 (correct answer)

Explanation: Direct labor = 80 hours x $25 =$2,000. Applied overhead = 80 hours x $18 =$1,440. Ending balance = $8,500 +$6,200 + $2,000 +$1,440 = $18,140. Option A omits applied overhead. Option B applies an incorrect overhead rate. Option C applies overhead to the beginning balance as well as current hours.

Question 10

1. $8.00 per equivalent unit
2. $9.00 per equivalent unit (correct answer)
3. $10.00 per equivalent unit
4. $7.50 per equivalent unit

Explanation: Under FIFO, cost per EU = Current period costs only / FIFO equivalent units = $189,000 / 21,000 =$9.00. FIFO excludes beginning WIP costs from the rate calculation, preserving the prior-period cost in the beginning WIP layer. Option A divides by 23,625. Option C divides by 18,900. Option D divides by 25,200.

Question 11

1. $105,000
2. $96,000
3. $77,000 (correct answer)
4. $124,000

Explanation: COGS includes only jobs completed and sold: Job #201 42,000 + Job #202 35,000 = $77,000. Option A includes Job #203 (finished goods, not sold). Option B includes Jobs 201, 202, and 203 minus Job 204. Option D includes all four jobs regardless of completion or sale status.

Question 12

1. $19,000
2. $47,000
3. $105,000
4. $28,000 (correct answer)

Explanation: Finished goods inventory includes only jobs that are complete but not yet sold. Only Job #203 ($28,000) meets this criterion. Option A reports Job #204, which is still in WIP, not finished goods. Option B sums Jobs #203 and #204 together. Option C totals Jobs #201 through #203, incorrectly including sold jobs.

Question 13

1. Job-order costing for both products because each production run incurs unique costs
2. Process costing for Product X and job-order costing for Product Y (correct answer)
3. Process costing for both products because they are manufactured in the same facility
4. Job-order costing for Product X and process costing for Product Y

Explanation: Process costing suits Product X because it is produced in homogeneous batches where costs are averaged across identical units. Job-order costing suits Product Y because each unit has unique specifications requiring separate cost accumulation per order. Option A incorrectly applies job-order to a homogeneous product. Option C incorrectly uses the shared facility as the basis for selecting the same system. Option D reverses the appropriate assignment.

Question 14

1. The product line has become more profitable and management wants more detailed tracking
2. The company wants to reduce administrative burden by simplifying its costing system
3. Process costing is required under GAAP for publicly traded manufacturers
4. The product line has shifted from standardized mass production to customized orders with significantly different resource requirements per unit (correct answer)

Explanation: The choice between costing systems should reflect the nature of the production process. When a product line transitions from homogeneous mass production to differentiated custom orders, the cost accumulation method should change accordingly - averaging costs across dissimilar jobs would distort product costs. Option A confuses profitability tracking with the basis for costing system selection. Option B incorrectly suggests job-order costing reduces administrative burden; it is typically more labor-intensive than process costing. Option C is incorrect; GAAP does not mandate a specific costing system.

Question 15

1. To express partially completed units as a number of fully completed units, allowing meaningful cost per unit calculations when some units are only partially processed (correct answer)
2. To determine the total number of units that will be transferred to finished goods inventory during the period
3. To reconcile the beginning and ending work-in-process account balances on the balance sheet
4. To calculate the predetermined overhead rate for the production department

Explanation: Equivalent units convert partially completed work-in-process into a common unit of measure comparable to fully completed units. Without this conversion, it would be impossible to calculate a meaningful cost per unit when some units in the period have only received 40% or 60% of the required processing. Option B describes the physical flow of units, not the purpose of equivalent units. Option C describes account reconciliation, which is a result of the process costing report, not the purpose of equivalent units. Option D describes predetermined overhead rate calculation, which is unrelated to equivalent units.

Question 16

1. A 50% estimate is statistically the most accurate because it represents the average completion for any production process
2. A 50% estimate is required under GAAP as a practical expedient for process costing
3. Using a fixed 50% estimate without regard to actual conditions will misstate equivalent units, cost per equivalent unit, and the cost assigned between completed units and ending WIP (correct answer)
4. The estimate is immaterial if ending WIP represents a small percentage of total production volume

Explanation: Equivalent units and the resulting cost per unit depend directly on the percentage of completion assigned to ending WIP. A fixed 50% applied regardless of actual conditions will overstate equivalent units in periods where WIP is less complete and understate them when WIP is more complete. This systematically distorts the cost split between completed units and WIP and affects the accuracy of inventory valuation and COGS. Option A has no analytical basis. Option B is incorrect; GAAP requires a reasonable estimate of actual completion, not a 50% rule. Option D is incorrect because the materiality conclusion depends on the dollar amount involved, not just the volume percentage.

Question 17

1. The plantwide rate always produces more accurate product costs than departmental rates in facilities with two departments
2. The company should increase direct labor in Department B to equalize the DLH mix between departments
3. Using a DLH rate overstates overhead applied to jobs processed primarily in Department A
4. Jobs processed primarily through Department B are likely under-costed because the DLH plantwide rate does not capture the machine-intensive overhead consumption of that department (correct answer)

Explanation: Department B's overhead ($600,000) is driven by machine activity (60,000 hours), but the plantwide DLH rate allocates overhead based on labor hours. Because Department B uses few DLH relative to its machine-heavy overhead, jobs spending significant time in Department B will receive less overhead allocation than their actual resource consumption warrants. A departmental overhead rate using machine hours for Department B would produce more accurate costs. Option A makes an absolute claim without analytical basis. Option B is an operational suggestion unrelated to the costing accuracy question. Option C reverses the direction; Department A, which uses most of the DLH, would absorb a disproportionately high share of machine-related overhead.

Question 18

1. Under weighted-average, total conversion costs to account for are $180,000 (beginning WIP costs plus current period); FIFO uses only the$162,000 of current period costs to compute cost per equivalent unit (correct answer)
2. Under weighted-average, total costs to account for are $162,000 and FIFO uses$180,000
3. Both methods use $180,000 as total costs, but compute equivalent units differently
4. Weighted-average and FIFO produce identical cost per unit results when beginning WIP is less than 20% of total units processed

Explanation: The weighted-average method blends beginning WIP costs with current period costs. Total costs to account for = $18,000 +$162,000 = $180,000, and this combined figure is divided by weighted-average equivalent units. FIFO keeps the cost layers separate: beginning WIP costs ($18,000) are assigned to the first units completed using prior-period rates, and only current period costs ($162,000) are divided by FIFO equivalent units to compute the current period rate. This means FIFO preserves cost period purity while weighted-average smooths costs across periods. Option B reverses which method uses which amount. Option C is incorrect; FIFO uses only$162,000 for the rate calculation. Option D is incorrect; the two methods will diverge whenever beginning WIP carries a different cost per unit than current period inputs.

Question 19

1. Underapplied overhead is favorable because actual overhead was less than the amount applied to jobs
2. The predetermined overhead rate is likely set too low, causing persistent underallocation that overstates profits during the year and requires a large corrective COGS adjustment at year-end (correct answer)
3. Disposing of underapplied overhead to COGS is prohibited under GAAP
4. The underapplied balance indicates the company ran below budgeted activity levels, which is unrelated to the rate setting process

Explanation: Underapplied overhead means actual overhead exceeded applied overhead. A consistent pattern suggests the predetermined rate is systematically too low - perhaps based on optimistic activity assumptions - rather than a one-time variance. During the year, job costs are understated (less overhead applied per job), which overstates gross profit and operating income. The year-end adjustment to COGS corrects this but creates volatility in reported results. Option A reverses the definition: underapplied means actual exceeded applied, which is unfavorable. Option C is incorrect; disposing underapplied overhead to COGS is an acceptable simplified treatment under GAAP when immaterial. Option D addresses one possible cause but not the management implication.

Question 20

1. 21,000 equivalent units (correct answer)
2. 22,800 equivalent units
3. 18,000 equivalent units
4. 23,000 equivalent units

Explanation: FIFO EUP = (Beginning WIP x % remaining) + (Units started and completed) + (Ending WIP x % complete). Units started and completed = 20,000 - 2,000 = 18,000. EUP = (2,000 x 60%) + 18,000 + (3,000 x 60%) = 1,200 + 18,000 + 1,800 = 21,000. Option B uses weighted-average logic by adding all completed units plus ending WIP at full percentage. Option C counts only units started and completed. Option D uses 100% for beginning WIP remaining work.
