Problem 2: Meal Planning You have to create a meal based on the macros for the following food items (portions of 100g): . fish: 25g of protein: 3g of fat: 0g of carbs. . beans: 20g of protein: 2g of fat: 60g of carbs. . spinach: 3g of protein: 1g of fat: 4g of carbs. Consider that the meal must contain 60g of protein, 10g of fat and 80 g of carbs. (a) Set up a system of linear equations that models the problem above. (b) Determine the number of portions for each food item that satisfies all these requirements. (c) Assume now. that you also want this meal to have 25ing of iron. You checked that the iron on the portions are: lig in the fish. bing in the beans. and Sing in the spinach. Is it possible to also attend this requirement? (d) How would you plan this meal if iron supplementation is available
