Answer: $6.70 per direct labor hour
Explanation:
Given that,
Estimated total manufacturing overhead = $134,000
Estimated total direct labor = 20,000 hours
Actual total manufacturing overhead for the year = $ 123,900
Actual total direct labor = 21,000 hours
Predetermined over rate for the year = [tex]\frac{Estimated\ manufacturing\ overhead}{Estimated\ direct\ labor\ hours}[/tex]
= [tex]\frac{134,000}{20,000}[/tex]
= $6.70 per direct labor hour
