conversations.value: Can you give me some step-by-step instructions for this math problem: Frank goes to the store to buy some food. He buys 5 chocolate bars and 2 bags of chips. He hands the cashier $20 and gets $4 back as change. If the chocolate bars each cost $2, how much did each bag of chips cost?
conversations.from: assistant
conversations.value: His entire purchase cost $20 - $4 = $16.
  The chocolate bars cost 5 * $2 = $10.
  The bags of chips cost a total of $16 - $10 = $6.
  Each bag of chips cost $6 / 2 = $3.
