4. A school is trying to decide what to feed the kids for lunch. They are trying to reduce their cost but meet the required nutrition for kids. The food items for lunch is listed in table-3. The nutrition content of each food and it's cost are shown in the table. It is required that each kid should receive between 400 and 600 calories for lunch. No more than 30 percent of total calories should come from fat. Also, each kid should consume at least 60 mg of vitamin C and 12 g of protein. Each kid needs two slices of bread to make the sandwich and at least twice as much peanut butter as jam. Also, each kid needs at least 1 cup of liquid (milk and/or juice). Formulate an LP to help the school manager to select the food choice for kids which minimize cost and meet all of the requirements.
