Identifying Cost Drivers in an ABC system Patterson makes electronic components for handheld games and has identified several activities as components of manufacturing overhead: factory rent, factory utilities, quality inspections, materials handling, machine setup, employee training, machine maintenance, inventory security costs, and supervisor salaries. For each activity that Patterson has identified, choose a cost driver to allocate that cost. Explain your reasoning.
