Answer:
Variable overhead efficiency variance= $135 favorable
Explanation:
Giving the following information:
Standard supplies cost $ 1.50 per machine-hour
Standard machine-hours per truck 2.9 machine-hours
Actual production of 3,800 trucks
Actual machine-hours 10,930 machine-hours
<u>To calculate the variable overhead efficiency variance, we need to use the following formula:</u>
Variable overhead efficiency variance= (Standard Quantity - Actual Quantity)*Standard rate
Variable overhead efficiency variance= (2.9*3,800 - 10,930)*1.5
Variable overhead efficiency variance= (11,020 - 10,930)*1.5
Variable overhead efficiency variance= $135 favorable
