Answer:
$10,095 Unfavorable
Explanation:
For computation of flexible-budget variance for variable manufacturing overhead first we need to find out the budgeted machine hours for 51,100 and standard variable manufacturing overhead which is shown below:-
Budgeted machine hours for 51,500 units = Budgeted machine-hours ÷ Budgeted output units × Actual output units produced
= 17,185 ÷ 49,100 × 51,100
= 17,885 hours
Standard variable manufacturing overhead = Budgeted machine hours for 51,500 units × (Total variable overhead ÷ Total machine hour)
= 17,885 hours × ($360,885 ÷ 17,185)
= 17,885 hours × $21
= $375,585
Flexible-budget variance for variable manufacturing overhead = Standard variable manufacturing overhead - Actual variable manufacturing overhead
= $375,585 - $385,680
= $10,095 Unfavorable
Therefore as per the answer the standard variable is lesser than actual variable manufacturing overhead so it will become unfavorable.
