Exhibit 4-1
A hospital emergency room requires different numbers of nurses on different days of the week. The number of full-time employees required to be working (i.e. not on call) each day is given in the table below.
$\begin{array}{|l|l|l|l|l|l|l|}\hline \text { Mon } & \text { Tue } & \text { Wed } & \text { Thu } & \text { Fri } & \text { Sat } & \text { Sun } \\\hline 18 & 15 & 12 & 13 & 20 & 28 & 22\\\hline \end{array}$ Hospital rules require that nurses work four consecutive days, are on call for one day, and then receive two days off.
