1 (6 points) - EXERCISE 7.11 from DMD textbook Dairy products are rich in many vitamins. However, when exposed to light even for brief periods of time, these vitamins tend to decompose, thus diminishing the nutritional value of dairy products. To avoid this undesirable effect, dairy products should be stored in specially designed packaging. WonderPlastics is a company specializing in producing plastic products designed to meet special customer requirements. In particular, they supply five local dairy farms with plastic packaging suitable for storing dairy products. The plastic packaging is produced at WonderPlastics' two plants located in Amherst and Providence. The unit production costs and weekly capacities of the plants are summarized in Table 7.46, and customer demands are shown in Table 7.47. The cost of supplying the customers is different for the two plants. The unit transportation costs (in $/unit) are shown in Table 7.48. The management of WonderPlastics must decide how many units of plastic packaging to produce at each of the two plants and how much of each customer's demand to supply from each plant, so as to minimize the total production and transportation cost
