This was a short project made to demonstrate a concept to some high school students who may (or may not) have been interested in pursueing a computer science field of study. The concept was that with a limited knowledge of programming you can get a computer to answer questions for you that otherwise would be either a) really tedious to try to work out on your own, b) impossible to work out on your own, or c) would require higher levels of maths to work out on your own. the problem is this: If gas prices are on the rise, is it cheaper to adopt the strategy of buying one day's worth of gas every day, or to just fill up completely and then burn it all off, and then buy more when you need to. this simple simulation tests two people who have identical cars and drive and identical amount, but one is a procrastinator that fuels up only when he has to and the other is a non-procrastinator that fuels up every chance she gets. The simulation shows that the non-procrastinator, buying exactly 1 gallon a day, at whatever the prices are that day, in the long run spends less money. And that the savings grow as the gas prices increase.
