4. Variable overhead
Rate variance:
This variance includes both price and quantity elements.
The overhead spending variance reflects differences between actual and
standard prices for variable overhead items. It also reflects differences
between the amounts of variable overhead inputs that were actually
has the indirect effect of reducing variable overhead. Because 2,000
fewer labor-hours were required than indicated by the labor standards,
the indirect effect was presumably to reduce variable overhead spending
by about $5,000 ($2.50 per hour × 2,000 hours).

5. The major disadvantage of using normal activity is the large volume
variance that ordinarily results. This occurs because the denominator
activity used to compute the predetermined overhead rate is different
from the activity level that is anticipated for the period. In the case at
hand, the company has used a long-run normal activity figure of 30,000
