Solve these problems using graphical linear programming and then answer the questions that follow. Use simultaneous equations to determine the optimal values of the decision variables.
a. Minimize Z = 1.80S + 2.20T
Subject to
Potassium 5S + 8T ≥ 185 gr
Carbohydrate 15S + 6T ≥ 240 gr
Protein 4S + 12T ≥ 180 gr
T T ≥ 10 gr
S,T ≥ 0
