Answer:
Underapplied overhead = $2,367,040
Explanation:
Predetermined overhead rate = Estimated overhead / Estimated activity
Predetermined overhead rate = $11,415,000 / 180,000
Predetermined overhead rate = $63.42 per MH
Applied overhead = Actual activity * Overhead rate
Applied overhead = 88,000 * $63.42 per MH
Applied overhead = $5,580,960
Overapplied/ (underapplied) = Actual overhead - Applied overhead
Underapplied overhead = $7,948,000 - $5,580,960
Underapplied overhead = $2,367,040
