Answer:
1. $30 per direct labor hours
2. $.15
3. $40 per machine hours
Step-by-step explanation:
The computation is shown below:
We know that
Predetermined overhead rate = (Total estimated manufacturing overhead) ÷ (estimated cost drivers)
So,
In the first case, the predetermined overhead rate equal to
= (Total estimated manufacturing overhead) ÷ (estimated direct labors hours)
= ($1,200,000) ÷ (40,000 direct labor hours)
= $30 per direct labor hours
2, In the second case, the predetermined overhead rate equal to
= (Total estimated manufacturing overhead) ÷ (estimated direct labors cost)
= ($1,200,000) ÷ ($800,000)
= $1.5
3. In the third case, the predetermined overhead rate equal to
= (Total estimated manufacturing overhead) ÷ (estimated machine hours)
= ($1,200,000) ÷ (30,000 machine hours)
= $40 per machine hours
