For instance, some goods are very<a href="https://www.investopedia.com/terms/e/inelastic.asp" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="2">inelastic</a>,that is, their prices do not change very much given changes in XXXXXX or demand, XXX example people need XX buy XXXXXXXX to get XX work or travel around XXX world, and so if XXX XXXXXX XXXX, XXXXXX will likely XXXXX buy just the same XXXXXX of XXX. On the XXXXX hand, XXXXXXX XXXXX are XXXX<a href="XXXXX://XXX.XXXXXXXXXXXX.com/terms/e/XXXXXXX.asp" data-XXXXXXXXX="link" XXXX-XXXXXX="inlineLink" XXXX-XXXX="internalLink" data-XXXXXXX="3">elastic</a>, their price moves XXXXX XXXXXXXXXXX changes in its demand or its supply.
