Question: Determine the solution space and the optimum solution of the Reddy Mikks model for each of the subsequent independent changes and employ the graphical approach.
Part 1: The maximum daily demand for exterior paint is at most 2.5 tons.
Part 2: The daily demand for interior paint is at least 2 tons.
Part 3: The daily demand for interior paint is exactly 1 ton higher than that for exterior paint.
Part 4: The daily availability of raw material M1 is at least 24 tons.
Find the solution space and the optimum solution of Reddy Mikks model and please show the working.
