I’m a bit weird with these sorts of arithmetic questions, my thought process went something like this: “Ok, 10 cents seems close, but that puts the bat at 90 cents more than the ball.. oh it seems like 5 cents and 1.05 works.” The answer just sort of pops into my head, not even thinking about the division step. Of course, I could do the simple maneuvering to get the answer, but it isn’t what I naturally do. I think this has to do with how I did math in grade school: I would never learn the formulas (and on top of this I would often forget my calculator) so I would rather come up with some roundabout method for approximating various calculations (like getting the root of a number by guessing numbers that “seemed close” to the root, usually starting at 1⁄2 the number and adjusting). Probably not really the best way to do things since there are much cleaner solutions, but this bad habit of arithmetic has sort of stuck with me through my mathematics degree (though I of course have picked up the relevant formulas by now!); instead of using the straightforward formula, I do this mental jiggling around of values and it pops into my head.
I don’t know, maybe that isn’t weird at all, but in any event no one has mentioned doing it yet.
