A section of the Excel output is shown below:

$\backslash$table$[[$Namp$,\backslash$table$[[$Final$],[$Walue$]],\backslash$table$[[$Reduced$],[$Cost$]],\backslash$table$[[$Objective Allowable$],[$Coefficlantlnciease$]],\backslash$table$[[$Allowable$],[$Decrease$]]],[$Produal A$,1500,0,20,40],[$Product $8,1000,0,300,60]]$

What will happen if the objective cocfricient for Product B increases to $400?$

The problem must be recalculated because the increase caused the range of fessibility to be exceeded.

The objective function value will change and the cptimal solution walues for the decision variables will alsochange.

$$ The problem must be recalculated because the increase caused the range of optimality to be exceeded. $q,$

$$ The objective function value will change, but the optimal solution values for the decision vaniables will remain the same:
