Answer:
$30 Favorable
Explanation:
Calculation for the activity variance for supplies cost in March
Using this formula
Activity variance = (Actual units - Budgeted units) * Variable cost
Where,
Actual units=856
Budgeted units=861
Variable cost=$6
Let plug in the formula
Activity variance=(856-861) * $6
Activity variance=5*$6
Activity variance=$30 Favorable
Therefore the activity variance for supplies cost in March would be closest to: $30 Favorable
