Lemonade Stand

From site:  Hi, and welcome to Lemonade Stand!  Your goal in this game will be to make as much money as you can within 7, 14 or 30 days.  To do this, you’ve decided to open your own business — a Lemonade Stand!  You’ll have complete control over almost every part of your business, including pricing, quality control, inventory control, and purchasing supplies.  You’ll also have to deal with the weather, which can be unpredictable.  Unfortunately, the weather will play a big part when customers are deciding whether or not to buy your product.
