Determine the solution space and the optimum solution of the Reddy Mikks model (from the lecture) for each of the following independent changes:
a) The maximum daily demand for exterior paint is at most 2.5 tons
b) The daily availability of raw material, M1, is at least 24 tons
c) The daily availability of raw material, M1, is at least 24 tons, and the daily demand for interior paint exceeds that for exterior paint by at least 1 ton.
Model Formulation and plot graph to approximate the solution for each case.
