Answer:
option (c) $6.40 per direct labor-hour
Explanation:
Data provided in the question:
Total fixed manufacturing overhead cost = $36,000
Variable manufacturing overhead = $2.80 per direct labor-hour
Direct labor-hours = 10,000
Now,
Fixed manufacturing overhead rate
= [ Fixed manufacturing overhead ] ÷ [ Direct labor hour ]
= $36,000 ÷ 10,000
= $3.6
Predetermine overhead rate
= Fixed manufacturing overhead rate + Variable manufacturing overhead
= $3.6 + $2.80
= $6.40 per direct labor-hour
Hence,
Answer is option (c) $6.40 per direct labor-hour
