In scheduling two drivers for delivering pizza, James needs to have at least 65 hr scheduled this week. His two drivers, Karen and Todd, are not allowed to get overtime, so each one can work at most 40 hr. Let x represent the number of hours that Karen can be scheduled, and let y represent the number of hours Todd can be scheduled.(See Example 7.)
a.Write two inequalities that express the fact that Karen and Todd cannot work a negative number of hours.
b.Write two inequalities that express the fact that neither Karen nor Todd is allowed overtime (i.e., each driver can have at most 40 hr).
c.Write an inequality that expresses the fact that the total number of hours from both Karen and Todd needs to be at least 65 hr.
d.Graph the feasible region formed by graphing the inequalities.
e.Is the point
f.Is the point
