Differentiate between a "change in quantity supplied" and a "change in supply."

Though the
phrases are very similar in their external appearance, they hold different meanings.A change in
quantity supplied is a simple phrase meaning the number of items you ordered has changed.Perhaps
you ordered 20 pieces from a supplier, but they were only able to provide 18.This would be a
change in quantity supplied.

A change in supply is much more general.This is
a broad term to denote something has differed in the supply that is being received.This could be
that the supplier has changed, or the type of item has changed.Perhaps there was a major
malfunction in trade routes and the item has been delayed by two weeks.All of these things would
be labeled as "changes in supply".
