Answer:
B. 6,000U
Explanation:
The total variable overhead variance shall be calculated using the following formula:
Variable overhead variance=(Actual units produced*Standard hours per unit* Standard rate per hour) - (Actual variable production overhead cost of actual production)
Standard rate per hour=$3
Standard hours per unit=2
Actual units produced=24,000
Actual variable production overhead cost of actual production=$150,000
Variable overhead variance=(24,000*2*3-150,000)
=(144,000-150,000)
=$6,000U
So the answer is B. 6,000U
