Answer:
$37,600 favorable
Step-by-step explanation:
Variable overhead spending variance can be computed as;
= (Actual hours worked × Actual variable overhead rate) - ( Actual hours worked - Standard variable overhead rate)
= ( 18,800 hours × $77,700/12,000) - (18,800 hours × $4.5)
= [(18,800 × $6.5) - (18,800 × $4.5)]
= $122,200 - $84,600
= $37,600 favorable
