Sacred Heart Hospital (SHH) faces skyrocketing nursing costs, all of which relate to its two biggest nursing service lines-the Emergency Room (ER) and the Operating Room (OR). SHH's current cost system assigns total nursing costs to the ER and OR based on the number of patients serviced by each line. Total hospital annual nursing costs for these two lines are expected to equal $3000,000. The table below show expected patient volume for both lines.
