A baker makes two types of bread loaves: "cottage" and "farmhouse".
  Let x be the number of cottage loaves and y be the number farmhouse loaves to be made each day.
  Each cottage loaf requires 500 grams of flour and 50 grams of butter.
  Each farmhouse loaf requires 300 grams of flour and 150 grams of butter.
  The baker has 4.5 kg of flour and 1.5 kg of butter available each day.
  The baker has time to bake at most 12 loaves.
  The baker makes a profit of 30p on each cottage loaf and 60p on each farmhouse loaf sold.
  How many of each type should be made each day to maximise potential profit?
  P = x + y          
  Enter two points for each constraint line to generate a plot in the window below.  
  You should choose points which clearly show the region formed by the constraints.  
  Constraint 1 x y          
  Point 1        
  Constraint 2 x y          
  Point 1        
  Constraint 3 x y          
  Point 1        
  Point 2        
  Constraint 4 x y          
  Point 1 8 8        
  Point 2 1 1
