Money Game

Eight participants, 100 days, and a shared pot of money amounting to 44.8 billion won (around 38 million USD). This is Money Game, a reality TV show, where participants try to spend as little as possible to walk away with as much as they can. Marooned in a specially designed TV set with nothing but a set of clothes and a rule book, every item they purchase is 1,000 times the original price. How much money will the participants manage to keep? (Source: WEBTOONS)
