Answer and Explanation:
The computation is shown below:
1. Overhead rates
For Molding Deptt
= Total Estimated overhead ÷ Total Machine hours
= $400,000 ÷ 5,000
= $80 per machine hour
For Polishing Deptt
= Total Estimated overhead ÷ Total Labor hours
= $80,000 ÷ 20,000
= $4 per machine hour
2. Overheads assigned to Form A is
= (80 × 3500) + (4 × 5000)
= $300,000
Overheads assigned to Form B is
= (80 × 1500) + (4 × 15000)
= $180,000
Now
Overhead cost per unit
Form A = $300,000 ÷ 30,000 = $10 per unit
Form B = $180,000 ÷ 50,000 = $3.6 per unit
