3. The overall unfavorable spending variance is a very small percentage of
the total cost, less than 0.4%. This suggests that costs are under
control. In addition, the pattern of the variances may reflect good
4. Average costs may not be very good indicators of the additional costs of
any particular production or performance. The averages gloss over
considerable variations in costs. For example, a production of Peter
Rabbit may require only half a dozen actors and actresses and fairly

Company A:
This company has a favorable volume variance because the
standard hours allowed for the actual production are greater
than the denominator hours.

This company has an unfavorable volume variance because
the standard hours allowed for the actual production are less
than the denominator hours.
Company C:
This company has no volume variance because the standard
