Q2. The following LP problem and its optimal final tableau are given as follows. If S1, S2 and S3 are slack variables for constraint 1,2 and 3 respectively, answer the questions below: independently: (LP):maxz=5x1+x2+23st.x1+x2+x366x1+x38x2+x32x1,x2,x30 a) Determine the basic variables from the optimal tableau given above. b) Do the Reduced Cost Analysis for the unprofitable activity (That means how we can make that activity just profitable)
