Earth's Best Light (EBL), a producer of energy-efficient light bulbs, expects that demand will increase markedly over the next decade. Due to the high fixed costs involved in the business, EBL has dec 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 $2.10 per bulb. Fixed manufacturing co $1,020,000 per year. Variable and fixed selling and administrative expenses are $0.40 per bulb sold and $240,000, respectively. Because its light bulbs are currently popular with environmentally cons EBL can sell the bulbs for $9.90 each. (Click the icon to view the capacity information.) Requirements 1. Calculate the inventoriable cost per unit using each level of capacity to compute fixed manufacturing cost per unit. 2. Calculate the production-volume variance using each level of capacity to compute the fixed manufacturing overhead allocation rate and this year's production of 260,000 bulbs. 3. Assuming EBL has no beginning inventory, calculate operating income for EBL using each type of capacity to compute fixed manufacturing cost per unit and this year's sales of 212,500 bulbs. Requirement 1 Begin by determining the formula to calculate the inventoriable cost per unit.
