Answer:
Variable manufacturing overhead rate variance= $8,078.2 unfavorable
Explanation:
Giving the following information:
Standard power rate $ 1.40 per machine-hour
Actual machine-hours (total) 62,140 machine-hours
Actual power cost (total) $ 94,989
To calculate the variable overhead rate variance, we need to use the following formula:
Variable manufacturing overhead rate variance= (standard rate - actual rate)* actual quantity
Actual rate= 94,989/62,140= $1.53
Variable manufacturing overhead rate variance= (1.4 - 1.53)*62,140
Variable manufacturing overhead rate variance= $8,078.2 unfavorable
