a) Rephrase this problem (except for the equality constraint) to fit our standard form of linear programming model.

b) Using the "big m" method, construct the first simplex tableau for the simple method and identify the corresponding initial (artificial) basic feasible solution. Also identify the initial basic variable that goes in and the basic variable that goes out
