George wishes to determine the number of daily servings (may be fractional) of pork and carrot that will meet this requirement at a minimum cost.

(a) Identify decision variables, objective function, and constraints and explain them in words, using at least 100 words

(b) Formulate a mathematical linear programming model using equations. Make sure you provide the exact descriptions of each variable and mathematical notations shown in the assignment guideline ppt.

(c) Solve a linear programming model for this problem on a spreadsheet, and interpret the results (meaning what is the optimal amount of daily serving for pork and carrot, and what is the minimum cost at the optimal servings of pork and carrot?), using at least 100 words
