Answer:
At the beginning of the year used in the predetermined overhead rate must have been $16.30 per labor hour
Explanation:
Estimated manufacturing overhead = $477,590
Actual Labor hours = 29,000
Actual Manufacturing overhead = $472,590
Over application of manufacturing overhead = $110
As we know:
Over applied manufacturing overhead = Manufacturing overhead applied - Actual manufacturing overhead
$110 = Manufacturing overhead applied - $472,590
Manufacturing overhead applied = $110 + $472,590
Manufacturing overhead applied = $472,700
Manufacturing overhead applied = Actual Labor Hours x Predetermined overhead rate
$472,700 = 29,000 hours x Predetermined overhead rate
Predetermined overhead rate = $472,700 / 29,000 hours
Predetermined overhead rate = $16.30 per labor hour
