conversations.value: Please show me the solution for: Tayzia and her two young daughters get haircuts.  Women’s haircuts are $48.  Children’s haircuts are $36.  If Tayzia wants to give a 20% tip to the hair stylist, how much would it be?
conversations.from: assistant
conversations.value: The two daughters’ haircuts cost $36 x 2 = $72.
  All three haircuts will cost $72 + $48 = $120.
  The tip on the haircuts is $120 x 20% = $24.
