The Plastechnics Company began operations several years ago. The company's product requires materials that cost $25 per unit. The company employs a production supervisor whose salary is $2,000 per month. Production line workers are paid $15 per hour to manufacture and assemble the product. The company rents the equipment needed to produce the product at a rental cost of $1,500 per month. The building is depreciated on the straight-line basis at $9,000 per year. The company spends $40,000 per year to market the product. Shipping costs for each unit are $20 per unit. The company plans to liquidate several investments in order to expand production. These investments currently earn a return of $8,000 per year. Required: Complete the answer sheet below by placing an "X" under each heading that identifies the cost involved. The "Xs" can be placed under more than one heading for a single cost, e.g., a cost might be a sunk cost, an overhead cost, and a product cost. Variable Cost Fixed Cost Direct Material Cost Direct Labor Cost Manufacturing Overhead Cost Period Cost Opportunity Cost Shipping cost Production Supervisor Salary Production Line Workers Wages Equipment rental Building depreciation
