Bartering died out?
Does this problem sound familiar?
"A lady exchanged with a friend 18 yd Damask at 3s 6d a yard for muslin at 14d a yard. How many yd of muslin did the lady receive?"
It was in an academic journal article, entitled "Bartering problems in arithmetic books 1450-1890". This particular problem was published in 1887, and was the last one that the author of the article could find in a book.
However, make some changes and you have "A bogger exchanged 18 balls of Rowan Damask for Patons Kroy Sock yarn in colorway Muslin. How many socks could she knit?"
