Zeitgeist Company manufactures silicon sleeves for MP3 players. In August of last year, Zeitgeist began producing the colorful sleeves. During the month of August, 16,000 were produced, and 14,750 were sold at $6.95 each. The following costs were incurred:

A selling commission of 8% of sales price was paid. Administrative expenses, all fixed, amounted to $37,890.
Required:
1. Calculate the unit cost and the cost of ending inventory under absorption costing. ( Note : Round unit cost to the nearest cent and cost of ending inventory to the nearest dollar.)
2. Calculate the unit cost and the cost of ending inventory under variable costing. ( Note : Round unit cost to the nearest cent and cost of ending inventory to the nearest dollar.)
3. What is the contribution margin per unit? ( Note : Round to the nearest cent.)
4. CONCEPTUAL CONNECTION Zeitgeist believes that multicolored sleeves will really take off after one year of sales. Management thinks sales this August will be twice as high as sales last August. Prepare an income statement for August of this year using the assumed higher level of sales. Which costing method should be used-absorption costing or variable costing?
