Answer:
b. $4,250 unfavorable
Explanation:
The computation of the variable factory overhead controllable variance is shown below:
= Actual variable factory overhead - standard variable factory overhead
where,
Standard variable factory overhead equals to
= 6,000 units × 1.5 standard hours per unit × $2.75 per hour
= $24,750
And, the other items values would remain the same
Now put these values to the above formula
So, the value would be equal to
= $29,000 - $24,750
= $4,250 unfavorable
