Answer:
The variance would be unfavorable.
Step-by-step explanation:
Variable overhead efficiency variance = (actual labor hours less budgeted labor hours) x hourly rate
As Actual labor hour increase that could be due to inefficient of workers, total variance will also increased. Inefficient Labor will spend more labor hours to complete a work. The actual Labor hour will be more than the budgeted labor hours. This will increase the overhead cost. The increase in any type of cost is unfavorable because it effects the margin. So the variance due to inefficiency of the workers are unfavorable for Canister Industries.
