I believe you that it works, but I'm totally shocked at this... surely everyone just starts rounding up to .75? It will add up! You've literally blown my mind with this; how do people carry on like this? It's like you've just told me up is down and down is up, I just do not comprehend at all how people can use this system?
Seriously, I know that sounds sarcastic but it's just thrown my brain.
Ever notice how gas stations usually give prices out to 1/1000 of a dollar (e.g, $3.459/gal) even though our smallest currency denomination is for only 1/100 of a dollar?
It happens with sales tax, too. In Chicago, the tax on a $29.99 video game is $2.924025. We'd just round down to $2.92, and the government lets that odd 0.4025¢ slide. It doesn't really add up, because there's also cases where the tax owed is something like $2.925975 and gets rounded up to $2.93.
Of course, if you pay via credit card or bank card other electronic means, as more and more people do even for small amounts, you pay the exact price.
