Answer:
variable overhead efficiency variance= $115 favorable
Step-by-step explanation:
Giving the following information:
The quantity standard is 1.5 hours per unit.
The variable overhead rate standard is $11.50 per hour.
In September, the company produced 1,400 units using 2,090 direct labor-hours.
To calculate the variable overhead efficiency variance, we need to use the following formula:
variable overhead efficiency variance= (Standard Quantity - Actual Quantity)*Standard rate
Standard quantity= 1.5*1,400= 2,100 hours
variable overhead efficiency variance= (2,100 - 2,090)*11.5
variable overhead efficiency variance= $115 favorable
