Solution:
According to the solution of exercise 14,
we have Maximize
Let’s construct a constrain table for the above
Table for (i)
Table for (ii)
Table for (iii)
On solving (i) and (ii), we obtain
It can be seen that the shaded region is the feasible region whose corner points are
Evaluating the value of
It is seen from the above table that the maximum value is 48000 .
So, the maximum value of
