Need c-e

Consider the problem and optimal tableau: mins.t.2x1x22x3x1x2+2x3102x1+x2x310x1,x2,x30 (a) Complete the optimal tableau. What is the optimal solution? (b) What is the optimal base B ? and B1 ? (c) Find the range for c1 (set to =2 ) where the solution remains optimal. (d) What is the change in the optimal objective value if b2 changes to b2=5 ? (e) What is the new optimal solution if we add to the problem a nonnegative variable x6 with c6=0 and A6T=(3,2)
