For calculate: single plant-wide overhead rate use direct working hours (DLH) as the allocation basis, and measure factory overhead.
Using DLH as the allocation basis to measure a single plant-wide overhead limit.
Single plant-wide overhead rate : 
=
For calculate: single plant-wide overhead rate use direct working hours (DLH) as the allocation basis, and measure factory overhead.
Using DLH as the allocation basis to measure a single plant-wide overhead limit.
Answer:
$300
