Answer:
213 Unfavorable
Explanation:
Given that,
Direct labor-hours used to produce this output = 2,130
Actual variable overhead rate = $6.10 per hour
Variable overhead per hour = $6.00
The variable overhead rate variance for July:
= Direct labor-hours used to produce this output × (Actual variable overhead rate per hour - Variable overhead per hour)
= 2,130 × ($6.1 - $6)
= 213 Unfavorable
