3. LINEAR PROGRAMMING PROBLEM Maximization with Sensitivity Analysis

By deploying three major operations (i.e, assembly, display, and warehousing), a company provides two types of products (R and S) to customers, generating a sales revenue of birr 110 and birr 90 per unit of each product respectively. Each unit of R demands 3 assembly hours and 8 m3 for warehouse. On the other hand, 5 assembly hours, 1 portable display, and 5 m3are demanded for 1 unit of product S. the maximum availability of assembly time, display, and warehousing space is 150 hours, 20 units, and 300m3respectively.The combined cost of these resources is $60 and $50 for each unit of products R and S respectively. Considerthe following table.
