            Mark was a successful auto mechanic.  He was so successful that he owned four auto repair garages.   One day he wanted to do an inventory of his business to see what he owned.  Each of the four garages contained four bays.  Each bay contained four toolboxes.  Each toolbox contained four socket wrenches and each wrench contained four sockets.  What is the total number of items in Mark’s business?


Good Luck!!!!!
