conversations.value: This math problem has got me stumped: Billy has $25 less than twice the money Sam has. If Sam has $75, how much money do they have together?
  Can you show me the way?

conversations.value: Billy has $25 less than twice Sam's money, or 2 * $75 - $25 = $150 - $25 = $125.
  Together they have $75 + $125 = $200.
