Mabley and Carew Inc. ship to their customers based on the following criteria. Orders of $100 or more receive free overnight shipping, orders between $50 and $100 receive free two-day shipping, and orders under $50 receive free standard postal shipping. However, customers using the Mabley and Carew Gold Credit Card are always given free overnight shipping regardless of the size of the order. If you were to construct a decision table to determine the shipping rate, how many Rules (columns) would there be?
