Many of the hospital's nurses are part$-$time employees. As a result, the hours of nursing care provided can be easily adjusted to the amount required at any particular time. The cost of wages and fringe benefits for nurses is approximately $$2,500$ for each block of $200$ patient days of care provided during a month. For example, nursing costs total $$2,500$ for $1$ to $200$ patient days, $$5,000$ for $201$ to $400$ patient days, $$7,500$ for $401$ to $600$ patient days, and so forth.
