Answer:
$18,100 unfavorable
Step-by-step explanation:
The computation of the total variable overhead variance is shown below:
Total variable overhead variance = Standard variable overhead cost - Actual variable overhead cost
where,
Standard variable overhead cost is
= 2 hours × 400 units × $8 per hour
= $6,400
And, the actual variable overhead cost is $24,500
So, the total variable overhead variance is
= $6,400 - $24,500
= $18,100 unfavorable
Since the actual variable overhead cost exceeds then the standard variable overhead cost so it reflects the unfavorable variance
