Plaese I like OTA #102862 help me to solve this problem.
Solve the following linear programing model graphically:
maximize Z= 5x1 + 8x2 subject to:
3x1 + 5x2 <(Greater or Iqual to)50
2x1 + 4x2 <(Greater or Iqual to)40
       x1 <(Greater or Iqual to)8
       x2 <(Greater or Iqual to)10
      x1,x2 > 0
Transform this model into standard form and indicate the value of the slack variables at each corner point solution.
