Answer:
Variable overhead efficiency variance $ 8,018 Unfavorable
Step-by-step explanation:
Variable overhead efficiency variance: Variable overhead efficiency variance aims to determine whether or not their exist savings or extra cost incurred on variable overhead as a result of workers being faster or slower that expected.
Since the variable overhead is charged using labour hours, any amount by which the actual labour hours differ from the standard allowable hours would result in a variance
Hours
2,700 units should have taken (2,700 × 3.20) 8640
but did take (actual hours) 9,400
Efficiency variance in hours 760 unfavorable
standard variable overhead cost per hour $10.55
Variable overhead efficiency variance $ 8,018 Unfavorable
Variable overhead efficiency variance $ 8,018 Unfavorable
