Answer:
$10,400 Favorable
Explanation:
The computation of overhead controllable variance is shown below:-
Overhead controllable variance is
= Standard overhead - Actual
= ((34,000 × $6) + (32,000 × $4)) - $321,600
= ($204,000 + $128,000) - $321,600
= $332,000 - $321,600
= $10,400 Favorable
Therefore for computing the overhead controllable variance we simply applied the above formula.
