i am asked to consider the following senario:

making a trail mix with particular ingredients: Peanuts, Raisins, M&Ms, Mini-preztels (x1+x2+x3+x4) respectively

Calories(kcal):855 ; 435 ; 1024 ; 162

Protein(g): 34.57; 4.67; 9.01; 3.87

Fat(g):72.5; .67; 43.95; 1.49

Carbs(g): 31.4; 114.74; 148.12; 33.86

( table listed is for a serving size of 1 cup )

make at most 10 cups, using all the ingredients. here's the catch.. so that the mix isn't dominated by any one ingredient, each ingredient will contribute at least (>= ) 10% of the total volume of the mix made

more constraints, x1+x2+x3+x4<= 7000 calories

Objective function: Max Carbs 31.4x1+ 114.74x2+ 184.12x3+ 33.86x4

considering this... how would i write the constraints when forming a Simplex tableau??

i am using excel for this problem.. but i think i am missing some constraints
