3. Lang Industries makes and sells two types of security systems: Standard and Supreme. The Standard system is the baseline system, and the Supreme system is the high-end system. The Standard system requires $30 in direct materials per unit and $20 in direct labor per unit. The Supreme system requires $70 in direct materials per unit and $5 in direct labor per unit. Currently, Lang Industries allocates overhead using direct labor costs. Lang Industries estimates overhead for the upcoming month will be $23,500, and estimates it will produce 100 units of the Standard system and 20 units of the Supreme system. The Standard system is produced in batches of 50 units. Units of the Supreme system are produced individually (batches of 1 unit). Required: a. Under its current costing system, what is the cost per unit of the Standard and Supreme systems for the upcoming month? b. Hope, the controller at Lang Industries, suggests updating the costing system to an activity- based costing system. Hope identifies three pools, as follows: Cost Pool Cost Pool Amount Activity Driver Labor Support Services $3,320 Direct Labor Cost Receiving and Handling Materials $16,520 Direct Materials Cost Setup and Inspection $3,660 # of Setups Under the activity-based costing system, what is the cost per unit of the Standard and Supreme systems for the upcoming month? c. Suppose the Standard system sells for $275 per unit, and the Supreme system sells for $450 per unit. Using the per-unit costs from part 2, calculate the profitability of one unit of each system. Do both systems generate a profit on a per-unit basis? If not, would you recommend discontinuing that product line? What information would you need before offering a recommendation?
