If you haven't seen it yet, Ray Camden is back at it again with a new Friday puzzler. This one involves creating a UDF to mimic a lemonade stand. Your code has to programmatically decide how many cups of lemonade to make and how much to sell them for based on your budget, the weather, temperature, and your cost.I am perfecting my algorithm that I think will work well. I will blog it after everyone turns in their entries. In the mean time, there is still time for you to submit your entry!
