Explanation: The activity variances are all favorable because the actual activity was less than the planned activity and therefore all of the variable costs should be lower than planned in the original budget.

Explanation: An unfavorable spending variance means that the actual cost was greater than what the cost should have been for the actual level of activity. A favorable spending variance means that the actual cost was less than what the cost should have been for the actual level of activity. While this makes intuitive sense, sometimes a favorable variance may not be good.
