conversations.value: John has a donkey and an elephant.  The elephant weighs 3 tons (a ton is 2000 pounds).  The donkey weighs 90% less.  What is their combined weight in pounds?
  Give me a solution to this problem

conversations.value: The elephant weighs 3*2000=6000 pounds
  The donkey weighs 6000*.9=5400 pounds less
  So the donkey weighs 6000-5400=600 pounds
  That means the combined weight is 600+6000=6600 pounds
