14 Consider the following LP and its optimal tableau

(Table 59):

a Find the dual to this LP and its optimal solution.
b Find the range of values of the right-hand side of the third constraint for which the current basis remains optimal.
Also find the new optimal solution if the righthand side of the third constraint were 15/2 15 Consider the following LP:

Use the graphical approach to determine the range of values for the right-hand side of the second constraint for which the current basis remains optimal.
