- Consider the following LP problem: Maximizeearnings=subjecttoX1+2X2+X3+5X4X24X3+8X46X1+7X2+2X3X4X1,X2,X3,X4$0.80X1+$0.40X2+$1.20X3$0.10X4150=701200 a. Convert these constraints to equalities by adding the appropriate slack, surplus, or artificial variables. Also, add the new variables into the problem's objective function. (20%) b. Set up the complete initial simplex tableau' for this problem. Do not attempt to solve. (20%)) c. Give the values for all variables in this initial solution. (10%))
