Below is the ontimal solution table for a dual model:

$\backslash$table$[[$Basic Variables,X$1,$X$2,$S$1,$S$2,$RHS$],[$X$2,0,1,1,1,8],[$X$1,1,0,1,2,4],[$Z$,0,0,1,1,32]]$

Answer question $9-11$

$9.$ The optimal solution value$($s$)$ for the decision variables in the dual model is:

a$)0$ and $0$

b$)1$ and $1$

c$)4$ and $8$

d$)32$

$10.$ the optimal value $($minimum or maximum value for the objective function for the original or primal model is :

a$)8$

b$)1$

c$)0$

d$)32$

$11.$ The optimal solution value$($s$)$for the decision variables in the primal model is:

a$)0$ and $0$

b$)1$ and $1$

c$)4$ and $8$

d$)32$
