Answer:
$666 Favorable
Step-by-step explanation:
The computation of Activity variance is shown below:-
For computing the activity variance first we need to compute the Planning budget and flexible budget
Planning budget = $35,900 + $11.10 × 3,650
= $76,415
Flexible budget = $35,900 + $11.10 × 3,590
= $75,749
Activity variable = Activity variance - Flexible budget
= $76,415 - $75,749
= $666 Favorable
