Answer:
A) $21.50 per machine hour
B) $40.80 per direct labor hour
Explanation:
A) factory 1 overhead ⇒ on the basis of direct machine hours.
overhead rate factory 1 = estimated total overhead costs factory 1 / estimated machine hours
= $12,900,000 / 600,000 machine hours = $21.50 per machine hour
B) factory 2 overhead ⇒ on the basis of direct labor hours.
overhead rate factory 2 = estimated total overhead costs factory 1 / estimated labor hours
= $10,200,000 / 250,000 labor hours = $40.80 per direct labor hour
