Corbertt Pharmaceuticals manufactures an over - the - counter allergy medication. The company sells both large commercial containers of 1,000 capsules to health-care facilities and travel packs of 20 capsules to shops in airports, train stations, and hotels. The following information has been developed to determine if an activity-based costing system would be beneficial: Other production information includes the following: Compute the cost allocation rate for each activity. Use the activity-based cost allocation rates to compute the activity costs per unit of the commercial containers and the travel packs. Corbertt's original single-allocation-base costing system allocated indirect costs to produce at $157 per machine hour. Compute the total indirect costs allocated to the commercial containers and to the travel packs under the original system. Then compute the indirect cost per unit for each product. Compare the indirect activity-based costs per unit to the indirect costs per unit from the single-allocation-base system. How have the unit costs changed? Explain why the costs changed.
