This analysis determined that occupants could be grouped into three categories (low, moderate, and high usage of OOA) and that the activity driver of OOA should be nursing hours. The driver of the residential space and meals is occupant days. The following quantitative information was also provided: Occupant Category Low usage Medium usage High usage Annual Occupant Days 36,000 18,000 6,000 60,000 Annual Nursing Hours 90,000 90,000 120,000 300,000 The total annual cost of OOA was $7.5 million, and the total annual cost of providing residential space and meals was $7.2 million. Accordingly, the ABC analysis indicates that the daily costing rate for providing residential space, meals, and OOA should be
