Lemonade anyone?

Ryan is always trying to find ways to make money. He enlisted his sister Katie to help him. He first wanted to sell 1 cup for $5. I had to explain that is to much. Then he went down to $1. I had to explain you could by a sode for that price, unless he was going to use bigger cups. He finally setteled on .15 cents for a cup. He made $4.20 that's after charging me for some. He had some people give him extra money for the effort. He thought that was cool. I had to explain to him that he owed me money for the cool aid and lemonade. But in the end I let him keep the money. He worked hard and had fun.
