Final answer:
The fixed overhead production-volume variance is $14,400 unfavorable. The fixed overhead spending variance is $9,000 unfavorable.
Step-by-step explanation:
The fixed overhead production-volume variance is calculated by subtracting the budgeted fixed overhead cost from the actual fixed overhead cost and multiplying it by the difference between the actual and budgeted production volume. In this case, the budgeted fixed overhead cost is $144,000, the actual fixed overhead cost is $153,000, and the difference between the actual and budgeted production volume is 3,000 units. Therefore, the fixed overhead production-volume variance is $14,400 unfavorable.
The fixed overhead spending variance is calculated by subtracting the budgeted fixed overhead cost from the actual fixed overhead cost. In this case, the budgeted fixed overhead cost is $144,000 and the actual fixed overhead cost is $153,000. Therefore, the fixed overhead spending variance is $9,000 unfavorable.
