Miller Corporation produces a single product. The company had the following results for its first two years of operation: In Year 1, the company produced and sold 40,000 units of its only product; in Year 2, the company again sold 40,000 units, but increased production to 50,000 units. The company's variable production cost is $5 per unit and its fixed manufacturing overhead cost is $600,000 a year. Fixed manufacturing overhead costs are applied to the product on the basis of each year's unit production (i.e., a new fixed manufacturing overhead rate is computed each year). Variable selling and administrative expenses are $2 Required: 1. Compute the unit cost for each year under absorption costing and under variable costing. 2. Explain why the net operating income for Year 2 under absorption costing was higher than the net operating income for Year 1, although the same number of units were sold in each year
