One serving of Shredded Wheat supplies 5 g of protein, 6 g of fiber, 160 calories and 1 g of fat. One serving of Crispix supplies 110 calories, 0.4 g of fat, 0.1 g of fiber, and 2 g of protein.
i) Set up the matrix B and the vector u such that Bu provides amounts of calories, protein, fiber, and fat contained in the mixture of 3 servings of Shredded Wheat and two servings of Crispix.
b. Assume that you wish the cereal with more fiber than Crispix but fewer calories than Shredded Wheat. Is it feasible for the mixture of two cereals to supply 3.20 g of protein, .64 g of fat, 130 calories and 2.46 g of fiber? If so, determine the mixture?
