conversations.value: Find the answer to the math problem: At a spa, Iris spent $400 to do her hair, 1/4 as much to do a manicure, and 3/4 as much money as a manicure to do a pedicure. How much money did she spend at the spa?
conversations.from: assistant
conversations.value: The total amount of money that Iris used to do a manicure is 1/4*$400 = $100
  Together, she used $400+$100 = $500 to do her hair and manicure,
  If Iris also spent 3/4 as much money as a manicure to do a pedicure, she used 3/4*$100 = $75 to do a pedicure.
  At the spa, Iris spent a total of $500+$75 = $575
