a) The graph of the inequalities is plotted as shown
The optimal solution is the point of intersection shown on the graph
b) If profit of is raised to $3 per unit, the profit maximising objective function becomes
The constraints however remain same.
The objective function is also depicted on the graph below along with the constraints
The optimal solution remains at . Hence optimal solution is not changed.
