I mean other than being too literal about the scenario and saying something like I would half flip the lever causing the trolley to derail. Then I would either just freeze and not act in time either way, or if I somehow had enough time to think it through, and I knew all the parameters with 100% certainty I don't think I would do it, $100 isn't that much money and thinking about my own financial gain when people are about to die would make me feel gross.
