Orlando Avionics makes three types of radios for small aircraft-Model A, Model B, and Model C. The manufacturing operations are mechanized, and there is no diredt labor. Manufacturing overhead costs are significant, and Orlando has adopted an activity-based costing system. Direct materials costs per unit for each model are as ollows: Model A $28 Model B $31 Model C $36 Orilando has three activities-assembly, materials management, and testing. Tide cost driver for assembly is machine hours. The cost driver for materials management ing is the number of units of product. Total costs and production volumes for the year were estimated as follows: Allocation Total cost Base Cost Driver Assembly $785,000 125,000 Machine hours OA, $49 O B. $146 . $122 OD, $150 Model B $31 Model C $36 has three activities-assembly, materials management, and testing.
