(c) What if the per-unit-cost of a shipment from origin 2 to destination 3 were to increase by $2, would that change the optimal solution? What if the cost were to decrease by $2?
(d) What would happen if the number of units available at the first warehouse were to be reduced by one unit? (Include cost considerations).
(e) What if we were offered extra units delivered to warehouse 2 at a rate of $2 per unit?
