Linear Programming Dse Past Paper [updated]

{x+2y≤207x−6y≤2013x+6y≥203 cases; Case 1: x plus 2 y is less than or equal to 20; Case 2: 7 x minus 6 y is less than or equal to 20; Case 3: 13 x plus 6 y is greater than or equal to 20 end-cases;

Here is where the DSE separates the Level 4 from the Level 5 student. Often, the optimal vertex is something like $(x = 33.3, y = 27.8)$. linear programming dse past paper
