Answer and Explanation:
1. The computation of Stamping Department and machine hours is shown below:-
Stamping department = Associated Overheads ÷ Total Direct Labor hours
= $120,000 ÷ 1,200
= $100
Plating Department = Associated Overheads ÷ Total Machine hours
= $104,000 ÷ 2,640
= $39.39
2. The computation of product factory overhead costs is shown below:-
Stamping Department = Direct Labor hour × overhead rate
Plating Department = Machine hours × Overhead rate
