Question 1180063: In the last two times around the game board, Wendell thought he was a goner. First, he had to pay ½ of his money in rent to somebody. He then had to pay $25 because of a “Chance” card. After that, he landed on another property where he had to pay 3/5 of his remaining money in rent. Fortunately, on his next turn he passed “Go” and collected $200. However, he landed on a property that wacked him for ½ of his money. Next, he got a “Chance” card and landed in jail. After he paid $50 to get out, the poor guy only had $70 cash left - no property, no nothing. How much money did he have at the beginning of this narrative?
