Answer:
b. $327
Step-by-step explanation:
The computation of the fixed portion is shown below:
But before that variable maintenance expense per direct labor is
= ($610 - $585) ÷ (34000 hours - 31000 hours)
= $0.00833 per direct labor hour
Now
Total variable expense for 34,000 hours is
= $0.00833 × 34000
= $283
And, finally Fixed portion is
= $610 - $283
= $327
