You have decided that for the next 10 Saturdays you will sell home-made Lemonade to make yourself some money with $10 your family have given you. Each Saturday you get a weather report and it is up to you to decide how many supplies you need to purchase. The supplies you require is sugar, lemon juice and cups. After your purchase you then decide how much to sell each cup of Lemonade. When you are happy with your decisions, you watch your supplies go down while hopefully your money climbs. At the end of the day the computer will advice you how you could of done better. Then it's the next Saturday and once again you decide how much supplies to buy and how much to sell a cup with your new weather report.
