Answer:
Fixed OAR= $3 per hour
Variable OAR = $2 per hour
Step-by-step explanation:
Predetermined overhead absorption rate is used to charged overheads to cost unit.
The rate is computed as follows
Overhead absorption rate (OAR) =Budgeted Overheads / Buffeted labour hours
Budgeted labour hours = Standard hour/unit × budgeted units/(normal capacity)
Fixed OAR
= $300,000/(1 × 100,000) hours
= $3 per hour
Variable OAR
= $200,000/(1× 100,000) hours
= $2 per hour
