We Are Not in the Money ...

I am supposed to go to Philly tomorrow. So I posted the kids' "Math Problems a la Mom" tonight. Oldest Twin's problem: Tom's salary is $200,000 annually. He spends 24% on food, 16% on electricity and other utilities, 21% on car and related expenses, and 19% on housing. How much $ does he spend on each area of expenses, and how much money does he have left to pay his 20% in taxes? Well, the oldest twin saw the problem already written out and had two questions: One, is Tom the brother of Jim from the previous problem, and just what do those two do for a living???
