Hello I need some help! Set a system of linear equations ( maybe 3 variables) for this problem. A nutritionist wants one of his patients to eat a meal with 66 grams of protein, 94.5 grams of carbohydrates and 910 milligrams of calcium. The food service of the hospital informs the nutritionist that the meal of the day is chicken, corn grains and 2% milk. Each serving of chicken has 30 grams of protein, 35 grams of carbohydrates and 200 milligrams of calcium. Each serving of corn has 3 grams of protein, 16 grams of carbohydrates and 10 milligrams of calcium. Each serving of 2% milk has 9 grams of protein, 13 grams of carbohydrates and 300 milligrams of calcium. How many servings of each food should be served to the patient?
