Answer:
$220 favorable
Step-by-step explanation:
In order to determine the activity variance for materials and supplies for the month of August,the budgeted amount needs to recalculated to reflect the actual level of activity.
What I meant by recalculating the budgeted amount is that we should recompute materials and supplies cost using budgeted prices but actual number of vehicles in the month.
Revised budgeted amount=$1960+($15*56)=$2800
But the amount incurred was $2,580
Activity variance for materials and supplies=$2800-$2580=$220 favorable
