C. Individual job or batch
D. Time period
🟢 Correct answer: C
🔴 Explanation: Job order costing accumulates costs for each distinct job, batch, or customer
order.

A. Actual overhead / actual activity
B. Estimated overhead / estimated activity
C. Actual overhead / estimated activity
D. Estimated overhead / actual activity
🟢 Correct answer: B
🔴 Explanation: The predetermined overhead rate uses budgeted (estimated) overhead

B. Underapplied by $15,000
C. Overapplied by $185,000
D. Underapplied by $200,000
, 🟢 Correct answer: B
🔴 Explanation: Actual overhead exceeds applied overhead by $15,000, meaning overhead is
underapplied.
Question 9
Equivalent units of production are used in:
A. Job order costing
B. Process costing
C. Variable costing
D. Absorption costing
🟢 Correct answer: B
🔴 Explanation: Equivalent units measure partially completed units in terms of fully completed
