Answer:
Activity variance= $150 favorable
Explanation:
Giving the following information:
Standard:
Fixed costs= $1,230
Variable cost per unit= $10
Actual:
The actual level of activity was 597 frames.
The actual supplies cost for the month was $7,050.
To calculate the activity variance, we need to use the following formula:
Activity variance= actual costs - standard cost*actual activity
Standard costs= 1,230 + 10*597= 7,200
Activity variance= 7,050 - 7,200
Activity variance= $150 favorable
