Subway Five Dollar Footlong

The main food sold by the [Subway] is Submarine sandwiches, sold in “Six-inch”, “Footlong”, and the new four inch “MiniSub” sizes.

The dollar (often represented by the dollar sign: “$”) is the name of the official currency in several countries, dependencies and other regions.

Some believe that the original measurement of the English foot was from King Henry I, who had a foot 12 inches long; he wished to standardise the unit of measurement in England. However this is unlikely, because there are records of the word being used approximately 70 years before his birth.
