conversations.value: I need help with this problem:
  The bananas at the supermarket cost $0.80 each, or a bunch for $3.00.  Jenny buys 10 bunches that average 4 bananas per bunch. How much money, in dollars, did she save by buying the bananas in bunches instead of individually?
conversations.from: assistant
conversations.value: Ten bunches makes 10*3=$30.
  There are 10*4=40 bananas.
  40 bananas would cost 40*0.80=$32 individually.
  She saved 32-30=2 dollars
