I assume you mean how much money you can get by playing. in that case, according to the system about $3000 or so. But it's a bit misleading since she technically gets $10k from the boss after she strikes a deal with Luke. But that $10k never shows up in her stats (assume they are deposited to the bank some how).What's the maximum amount of cash you can have?
However, after a while when you have a $1000+ or so, money does not mater any more for your ability to progress the game. There are simply no quests or things you need or can spend that kind of money on...
Other stats are much more important for your game progression , like dirty whore score, relationship scores, cheating big score, loving wife score etc...
