Help in Thrillville off the Rails for PC!!

[Raulrct]

Hello!! I have a serious problem in Thrillville Off the Rails, the money. I do not know happens that money is spent. And what I do is buy expensive attractions, but in theory the money I would have to recover because people enter them. I put the price 0.50 cents, I have to upload at a price of 1.00?? Because sometimes get more than 1.00 and people do not come because they are expensive, for example I raise the price to 2.00 and people do not go, why??
