tried solving requirement 1 but you can resolve it

Global Best Light (GBL), a producer of energy-efficient light bulbs, expects that demand will increase markedy over the next decade. Due to the high fixed costs involved in the business, GBL has decided to evaluate its financial performance using absorption costing income. The production-volume variance is written off to cost of goods sold. The variable cost of production is $2.70 per bulb. Fixed manufacturing costs are $1,020,000 per year. Variable and fixed selling and administrative expenses are $0.20 per bulb sold and $270,000, respectively. Because its light bulbs are currently popular with environmentaly conscious customers, GBL can sell the bulbs for $9.50 each. GBL is deciding among various concepts of capacity for calculating the cost of each unit produced. Its choices are as follows: IfIE (Click the icon to view the capacity information.) Data table Requirement 1. Calculate the inventoriable cost per unit using each level of capacity to compute fixed manufacturing cost per unit. Begin by determining the formula to calculate the inventoriable cost per unit. (Abbreviations used: mfg = manufacturing, admin. = administration.) +[ Now calculate the inventoriable cost per unit at each level of capacity. Requirement 2. Suppose GBL 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-) Requirement 3. Assume GaL has no beginning inventory. If this year's actual sales are 212,500 bulbs (and production is 250,000 bulbs), calculate operating income for GBL using each type of capacity to compute fixed manufacturing cost per unit. Calculate the operating income for each type of capacity. We will do the operating income calculations one at a time, beginning with theoretical. Label each variance as favorable (F) or unfavorable (U)
