You are a manufacturer able to produce two types of mobile phone, a budget model and a high-end model, to be released in a particular region where you know the demand for these phone models. For simplicity, reducing the problem scope to two dimensions, aumme production requires just two resources to produce a phone. the production lead time in minutes, and the material (subassemblies) required. Note that resources are subject to capacity constraints (i.e. resources are limited). Then assume 2500 minutes production lead time of in a month and 4800 units of input material (subassemblies). The required resources per phone, the demand per month and the sales price for a phone of each model are given below. Model and solve as a linear program using the graphical method. First outline the steps you will follow. Then solve the problem using LPSolve and compare against your solution using the graphical method.
