             Minimum Transportation cost is Tshs 40,600

              Warehouse 1           50     150     0
              Warehouse 2           100     0     200

             The minimum cost is Tshs 236,000


          11. (a)   The objective function is  Min z =  (40x +  20 ) 45200y +
             (b)   Inequalities associated to the transportation problems are
                 xy+ ≤  160
                 xy+ ≥  50          (c) The problem is not balanced
                 x ≤ 70                 since total supply from sources is
                  y ≤ 120               not equal to the total demand.
                 x ≥  0, y ≥  0

          12. (a)  Min f =  400x +  240y +  5120000
                 Subject to : x ≤  4000
                            y ≤  3 000

                               y
                            x +≥   6000
                               y
                            x +≤   4000
                            x ≥  0, y ≥  0
             (b)   The problem is balanced since total demand is equal to   total
                 supply. That is;
                   Total supply is  6000 + 3000 = 9000 bricks.
                   Total demand is  4000 + 3000 + 2000 = 9000 bricks.
