Required information (The following information applies to the questions displayed below.) Pants R Us is a subsidiary of Gap Inc. and specializes in designing and making unique and fashionable pants. To make each pair of pants, the cost includes direct materials, labour and manufacturing (factory) overhead, which are all typical costs of producing pants. Pants R Us has a strategy of tracing all its direct cost back to every single pair of pants, and overhead costs are assigned to the pants manufactured based on direct labour hours. Information about the production of pants are as follows: 1. In September 2020, Pants R Us budgeted $12,600 variable factory overhead cost and 2,250 direct labor hours to manufacture 4,500 pairs pants. 2. Pants R Us used 3,100 direct labor hours in September 2020 to manufacture 4,400 pairs of pants 3. Total spending on variable overhead during September 2020 was $16,200. 4. Pants R us budgeted $90,000 in September 2020 for fixed factory overhead costs. 5. The factory's practical capacity is 2,250 direct labor hours per month (to manufacture 4,500 pairs of pants). 6. Pants R Us incurred $92,400 in actual fixed overhead cost for September 2020. Assume that Pants R Us currently uses a four-variance analysis of the total factory overhead cost variance. However, management is considering the shift to a three-variance analysis. Required: 1. Compute Pants R Us' total overhead spending variance, the (variable overhead) efficiency variance, and the production volume variance for September 2020 and indicate whether each variance is favorable (F) or unfavorable (U). 2. Prepare the journal entries at the end of September 2020 to record each of the following: (a) the total overhead spending variance, (b) the (variable overhead) efficiency variance, and (c) the production volume variance. Within your journal entries, assume that all overhead costs are recorded in a single account called "Factory Overhead
