The Gutehi Company manufactures purses, shaving bags, and backpacks. The construction ineludes leather and synthetics, leather being the scarce raw material. The production process requires two types of skilled labor: sewing and finishing. The following table gives the availability of the resources, their usage by the three products, and the profits per unit. Estimate the optimum solution. Next, indicate whether the following changes in the resources will keep the current solution feasible. For the cases where feasibility is maintained, determine the new optimum solution (values of the variables and the objective function). (a) Available leather is increased to 45ft2. (b) Available leather is decreased by 1ft2. (c) Available sewing hours are changed to 38hrs. (d) Available sewing hours are changed to 46hrs
