I think I found the secret to this game. I started over so my angel investors could "help" me. I focused only on my lemon aid stand and upgraded it to 300 and the price stayed reasonable. Then I went to the newspaper-before I did I bought the manager and the upgrade-before I bought the newspaper itself. The prices stayed reasonable and I was able to reach 300 quickly that way. It was really quick then. Try this it worked really nicely.
