Required:1. Classify each activity cost as output unit-level, batch-level, product- or service-sustaining, or facility sustaining. Explain each answer.2. Calculate the cost per test-hour for HT and ST. Explain briefly the reasons why these numbers differ from the $20 per test-hour that CoreTech calculated using its simple costing system.3. Explain the accuracy of the product costs calculated using the simple costing system and the ABC system. How might CoreTech’s management use the cost hierarchy and ABC information to better manage its business?Output unit-level costs a. Direct-labor costs, $276,000 b. Equipment-related costs (rent, maintenance, energy, and so on), $495,000These costs are output unit-level costs because they are incurred on each unit of materials tested, that is, for every hour of testing. Batch-level costs c. Setup costs, $630,000These costs are batch-level costs because they are incurred each time a batch of materials is set up for either HT or ST, regardless of the number of hours for which the tests are subsequently run. Service-sustaining costs d. Costs of designing tests, $399,000These costs are service-sustaining costs because they are incurred to design the HT and ST tests, regardless of the number of batches tested or the number of hours of test time.
