Answer:
$4,250 unfavorable
Explanation:
For the computation of variable factory overhead controllable variance first we need to determine the standard variable factory overhead which is shown below:-
Standard variable factory overhead is
= 6,000 units × 1.5 standard hours per unit × $2.75 per hour
= $24,750
Variable factory overhead controllable variance = Actual variable factory overhead - standard variable factory overhead
= $29,000 - $24,750
= $4,250 unfavorable
Therefore we applied the above formula.
