5. Procedure: Problem 1. Assume that a small machine shop manufactures two models, standard and deluxe. Each standard model requires two hours of grinding and four hours of polishing, each deluxe module requires five hours of grinding and two hours of polishing. The manufacturer has three grinders and two polishers. Therefore in 40 hours week there are 120 hours of grinding capacity and 80 hours of polishing capacity There is a contribution margin of $3 on each standard model and $4 on each deluxe model. To maximize the total contribution margin, the management must decide on: 1.) the allocation of the available production capacity to standard and deluxe models 2.) the number of units of each model to produce
