conversations.value: Carmen needs $7 more to have twice the amount of money that Jethro has. Meanwhile, Patricia has $60, which is 3 times as much as Jethro. What is the sum of all their money?
  Give me a clear explanation.

conversations.value: Jethro has 60/3 = $20.
  Twice of what Jethro has is $20 x 2 = $40
  Carmen has $40 - 7 = $33
  The sum of all their money is $60 + $20 + $33 = $113
