Answer:
True
Explanation:
You made two different orders for a particular item and there is a difference between them, a decision maker will want to see the difference between the two orders and in most cases choose the order with the cheaper price by looking at the differential cost than the full cost, I.e trying to see the difference between the two orders or cost and to decide which one is cheaper. So it is true a decision maker will look at the difference between the two cost not the full cost of the orders.
