Question

The Subway Way Super Sandwich Challenge. This challenge entails eating and drinking only at Subway for one day. The catch is that you must stay within the required minimum and maximum daily allowance for Fat, Carbohydrates, and Calories.

From the Subway Menu (https://www.subway.com/en-US/MenuNutrition/Menu/All), select any three meal items (no beverages). Record the Fat, Carbohydrate, and Calorie contents for each.

Now, determine the daily recommended intake of each of these three nutrients (http://www.mydailyintake.net/daily-intake-levels/). While the intake varies from person-to-person, let's say that you have a 15% margin on each of these. For example, the recommended daily intake of nutrient X is 100 grams, then we will say your minimum is 85 grams and your maximum is 115 grams.

Your objective is this: eat as many meals as you can (maximize the total), SUBJECT to the nutritional constraint minimums and maximums. You are to write a linear programming problem, explain your constraints in verbal and mathematical form, and use the Simplex Method Tool (http://www.zweigmedia.com/RealWorld/simplex.html) to determine what you can eat.
