Answer:
1. $28
2. $278,040
3. $7,560 under-applied
4. $8.8536
Explanation:
The computation is shown below
1. Predetermined overhead rate = (Total Budgeted: Overhead) ÷ (estimated direct labor-hours)
= $285,600 ÷ 10,200 hours
= $28
2. The applied overhead would be
= Actual direct labor-hours × predetermined overhead rate
= 9,930 hours × $28
= $278,040
3. The over applied or under applied would be
= Actual manufacturing overhead - applied overhead
= $285,600 - $278,040
= $7,560 under-applied
4. Total cost per unit would be
= (Prime Cost + Applied Overhead) ÷ (Number of units)
= ($1,050,000 + $278,040) ÷ (150,000 units
= $1,328,040 ÷ 150,000 units
= $8.8536
