Answer:
$249 per machine hour
Explanation:
Given that,
Department 1:
Manufacturing overhead costs = $700,000
Direct labor hours = 80,000 DLH
Machine hours = 3000 MH
Department 2:
Manufacturing overhead costs = $1,040,000
Direct labor hours = 100,000 DLH
Machine hours = 4000 MH
Therefore,
Total manufacturing overhead:
= Manufacturing overhead of Department 1 + manufacturing cost of department 2
= $700,000 + $1,040,000
= $1,740,000
Total machine hours:
= Machine hours of department 1 + Machine hours of department 2
= 3,000 MH + 4,000 MH
= 7,000 MH
Manufacturing overhead rate per hour of both the department:
= Total manufacturing overhead ÷ Total machine hours
= $1,740,000 ÷ 7,000 MH
= $249 per machine hour
