Answer:
Variable overhead efficiency variance $1,680 Favorable
Explanation:
<em>Variable overhead efficiency variance: Variable overhead efficiency variance aims to determine whether or not their exist savings or extra cost incurred on variable overhead as a result of workers being faster or slower that expected. </em>
Since the variable overhead is charged using labour hours, any amount by which the actual labour hours differ from the standard allowable hours would result in a variance
Hours
5000 units should have taken (5000×0.5 hours) 2,500
but did take <u>2,080</u>
Labour hours variance 420 favorable
Standard variable overhead rate <u>×$ 4.00</u> per hour
Variable overhead efficiency variance <u>$1,680 Favorable</u>
