All-Natural Cereals makes three breakfast cereals, A, B, and C, from four high-quality all- natural ingredients: rolled oats, raisins, shredded coconuts, and slivered almonds. The monthly availabilities of the four ingredients are 30 tons, 3 tons, 3 tons, and 3 tons, respectively (1 ton = 2000 pounds). The corresponding costs per ton are $1,500, $3,000, $2,700 and $4,000. Cereal A is a 50:7:3 mix of oats, raisins, and almonds, cereal B is a 50:7:3 mix of oats, coconuts, and almonds, while cereal C is a 9:1:1:1 mix of oats, raisins, coconut and almonds. The cereals are produced in large 2.5-lb bags. Cereals A, B, and C are sold for $4.75, $5.25 and $6.0 per bag, respectively. The monthly demand for the three cereal types is estimated at 15,000, 18,000 and 12,000 bags, respectively. Beyond the ingredient costs, an additional variable cost of $0.5 is incurred for preparing each bag of cereal.
