Final answer:
The student inquired about the fixed-overhead volume variance for Benson Company. Based on the provided data and standard costing methods, the variance is $35,000 unfavorable, which doesn't match any of the given options.
Step-by-step explanation:
The student is asking about the fixed-overhead volume variance for Benson Company which can be calculated using the budgeted fixed overhead and the standard hours for the actual production. In this case, Benson Company budgeted $600,000 of fixed overhead based on 40,000 machine hours. With 10,000 units produced and a standard production time of 3.9 machine hours per unit, the standard hours for actual production would be 39,000 hours (10,000 units * 3.9 hours/unit). The fixed overhead rate is $15 per machine hour ($600,000/40,000 hours). The standard fixed overhead cost for the actual production is therefore 39,000 hours times $15 per hour, which equals $585,000. The actual fixed overhead is $620,000, so the variance is $620,000 - $585,000, which equals $35,000 unfavorable. However, since only options for $10,000, $15,000, and $20,000 variances are given, it appears there may be a mistake in the question as presented. Using the options provided, none precisely match the calculated variance of $35,000.
