Answer:
Variable overhead flexible budget variance
= (variable overhead rate x Actual output) - Actual variable overhead cost
= ( $8 x 25,000 units) - $210,000
= $10,000(A)
Explanation:
Variable overhead flexible budget variance is the difference between budgeted variable overhead cost and actual variable overhead cost. Budgeted variable overhead cost is obtained by the product of variable overhead rate and actual output.
