Maximise the function P =  22 x +  y subject to the following constraints:  
  2 x + 6 y 24  
   10 x + 4 y 20  
  20 x + y   18  
  x, y ≥ 0      
  Enter two points for each constraint line to generate a plot in the window below.  
  You will see "yes" if your point lies on the constraint line and "no" if not.   
  A "yes" does not imply the point is a "good" one! Make the region clear to see!  
  Constraint 1 x y          
  Point 1        
  Constraint 2 x y    
  Point 1      
  Constraint 3 x y        
  Point 1      
  Point 2

  Starting with the corner point nearest the origin, (0, 0), enter the corner points in clockwise order:
  Give your answers rounded to 2 decinmal places.          
  Calculate "P" based on your rounded answers.          
  Feasible Region Corner Points x y P  
  Corner Point 1  
  Corner Point 2  
  Corner Point 3  
  Corner Point 4  
  The objective function is maximised at corner point number:
