I guess the last one. Mainly from the point of view of discovering some kind of supermarket price policy (someone claimed that one day olives are up and fetta down, then the other day the opposite happen. you can replace fetta+olives with salt+pepper, tomato+cucumber, chicken+noodles and on to bigger groups, etc.etc.

Anyway, the interesting question is what you asked: can the intersection of M hyperplanes in N dimensions be solved as a linear algebra problem, perhaps by the simplex algorithm. Will it be faster?
