Answer:
Option (D) is correct.
Explanation:
Given that,
Supplies cost = $1,720 per month
For the month of March,
Company planned for activity = 612 frames
Actual level of activity = 616 frames
Activity variance = Planning budget - Flexible budget
= [(612 × 10) + 1720] - [(616 × 10) + 1720]
= $7,840 - $7,880
= 40 U
