conversations.value: Can you guide me through solving this problem: Tim had a birthday party with a clown that cost $100 an hour for 4 hours.  He also rented a bounce house for half the time that cost 3 times as much an hour. Everything else for the party cost $1000.  How much did his birthday cost?
conversations.from: assistant
conversations.value: The clown cost 100*4=$400
  The bounce house cost 100*3=$300 per hour
  He rented it for 4/2=2 hours
  So it cost 300*2=$600
  That means the total cost was 400+600+1000=$2000
