St. Mark's Hospital contains 450 beds. The average occupancy rate is 80% per month. In other words, on average, 80% of the hospital's beds are occupied by patients. At this level of occupancy, the hospital's operating costs are $32 per occupied bed per day, assuming a 30-day month. This $32 figure contains both variable and fixed cost elements (a) Estimate the variable cost per occupied bed on a daily basis using the high-low method. (b) Estimate the total fixed operating costs per month using the high-low method. Assume an occupancy rate of 70% per month. What amount of total operating cost would you expect the hospital to incur? (Omit the "$" sign in your response.)
