Answer:
$3,999.04 F
Explanation:
Calculation to determine the flexible-budget amount for variable manufacturing overhead?
First step is to calculate the Budgeted fleet hours per unit
Budgeted fleet hours per unit = 568 ÷ 710
Budgeted fleet hours per unit = 0.8
Second step is to calculate the Budgeted fleet hours allowed for 660 truckloads
Budgeted fleet hours allowed for 660 truckloads
Budgeted fleet hours allowed for 660 truckloads = 660 × 0.8
Budgeted fleet hours allowed for 660 truckloads = 528
Third step is to calculate the Budgeted variable overhead rate per machine hour
Budgeted variable overhead rate per machine hour = $89,460 ÷ 528
Budgeted variable overhead rate per machine hour = $169.43
Fourth step is to calculate the Flexible-budget amount
Flexible-budget amount = 528× $169.43
Flexible-budget amount= $89,459.04
Now let calculate the Flexible-budget variance
Flexible-budget variance = $85,460 − $89,459.04
Flexible-budget variance= $3,999.04 F
Therefore the Flexible-budget variance is $3,999.04 F
