concepts of capacity for calculating the cost of each unit produced. Its choices are as follows: (Click the icon to view the capacity information.) Requirement 2. Suppose PLF actually produces 250,000 bulbs. Calculate the production-volume variance using each level of capacity to compute the fixed manufacturing overhead allocation rate. Determine the formula that is used to calculate the production-volume variance. (Abbreviation used: mfg= manufacturing.) Next calculate the production-volume variance at each level of capacity. Label each variance as favorable (F) or unfavorable (U). nata table Question Viewer Requirements 1. Calculate the inventoriable cost per unit using each level of capacity to compute fixed manufacturing cost per unit. 2. Suppose PLF actually produces 250,000 bulbs. Calculate the production-volume variance using each level of capacity to compute the fixed manufacturing overhead allocation rate. 3. Assume PLF has no beginning inventory. If this year's actual sales are 212,500 bulbs (and production is 250,000 bulbs), calculate operating income for PLF using each type of capacity to compute fixed manufacturing cost per unit
