conversations.value: Cecil has $600. Catherine has $250 less than twice as much as Cecil while Carmela has $50 more than twice Cecil's money. How much money do they have altogether?
  Give me a solution to this problem

conversations.value: Twice as much as Cecil's money is $600 x 2 = $1200.
  So, Catherine has $1200 - $250 = $950.
  While Carmela has $1200 + $50 = $1250.
  Hence, they have a total of $600 + $950 + $1250 = $2800.
