Stream of consciousness rationale: 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.
The question and answer pair are described below.
Q: 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?
