conversations.value: Can you break down the solution for me for this math problem: Tim decides to get animals for his zoo.  He buys 3 goats for $400 each.  He gets twice as many llamas which cost 50% more each.  How much did he spend?
conversations.from: assistant
conversations.value: The goats cost 3*400=$1200
  He buys 3*2=6 llamas
  Each llama cost 400*1.5=$600
  So he spends 600*6=$3600 on llamas.
  So the total cost was 1200+3600=$4800
