Answer:
To calculate the predetermine overhead rate
Step-by-step explanation:
As we know that
Predetermined overhead rate = (Total estimated manufacturing overhead) ÷ (estimated direct labor-hours or estimated machine hours)
Plus if we talk about the manufacturing overhead, it is an indirect cost which could not be easy to trace the cost to a specific job or task
And the fixed cost would remain unchanged although the number of production units changes and the average cost per unit also changes due to changes in the production level
These reasons could be the greatest challenge.
