OR Exam II: Model Answer — Linear Programming & Graphical Optimization

This is my professionally crafted solution to a second-year Operations Research college exam at Fayoum University, Faculty of Computers and Information. The exam covered two Linear Programming problems — formulating LP models, applying the graphical method, identifying feasible regions, and evaluating corner points to find optimal solutions. Rather than submitting a handwritten answer, I built a fully structured HTML document to present my solution with publication-level clarity: step-by-step mathematical workings, custom SVG constraint graphs, corner-point evaluation tables, and clearly marked optimal answers — all styled with a clean editorial design using IBM Plex and Playfair Display typefaces.
