Answer:
Variable overhead efficiency variance= $544 favorable
Explanation:
Giving the following information: 
Variable overhead 0.90 hours $ 3.40 per hour 
Actual output 4,400 units 
Actual direct labor-hours 3,800 hours 
<u>To calculate the variable overhead efficiency variance, we need to use the following formula:</u>
<u></u>
Variable overhead efficiency variance= (Standard Quantity - Actual Quantity)*Standard rate
Variable overhead efficiency variance= (3,960 - 3,800)*3.4
Variable overhead efficiency variance= $544 favorable
Standard quantity= 4,400*0.9= 3,960

Answer:
Asper Corporation has provided the following data for February. Denominator level of activity 7,700 machine-hours Budgeted fixed manufacturing overhead costs $ 266,420 Fixed component of the predetermined overhead rate $ 34.60 per machine-hour Actual level of activity 7,900 machine-hours Standard machine-hours allowed for the actual output 8,200 machine-hours Actual fixed manufacturing overhead costs $ 259,960 The budget variance for February is $6,460 Favorable.
Explanation:
Budgeted fixed manufacturing overhead cost = $266,420.
Actual fixed manufacturing overhead costs  = $259,960
The budget variance for February is calculated as below:
Budget Variance = Actual Fixed Manufacturing Overheads - Budgeted Fixed Manufacturing Overheads
Budget Variance =$259,960 - $ 266,420.
Budget Variance = -$6,460
Budget Variance = $6,460 Favorable
