The activity variance for plane operating costs in October would be closest to $4,727 F .
Option D is correct.
<h3>Activity variance :</h3>
Activity deviation is the difference. Between a revenue or cost item in a variable budget and the same item in a static plan budget. Performance deviation arises only from the difference between the actual service coverage of the flexible budget and the expected service coverage of the planning budget.
<h3>Evaluating activity variance :</h3>
Plane operating costs in planning budget :
= 48840+(2381 × 63)+(7× 293)
$ 200894
Less: Plane operating costs in flexible budget
= 48840+(2381 × 61)+(7× 298)
$196167
Activity variance for Plane operating costs = $200,894 - $196,167
= $4,727.
Activity variance is $4,727 F .
<h3>What is the purpose of activity variance?</h3>
Differences in activity are important for managerial decision-making. This is the difference between static and flexible budget cost items. This shows the cost difference between planned and flexible budgets.
