In Chapter 3, Evan and Scott embark on a joint venture to sell lemonade together. Scott’s attitude frustrates Evan, and he wishes that one of his other friends had been home instead. As they bring the cooler down the street, Evan and Scott argue briefly about where to locate their lemonade stand, with Evan pushing for the corner since he learned last summer from Jessie that it was the best location for foot traffic. While they wait for customers, both boys drink some of the lemonade, though Scott drinks more than Evan.

Over the course of the day, Scott drinks more and more lemonade, and they manage to sell 14 cups to customers. Evan tries to calculate how much money they’ve earned but can’t figure out how to do the math correctly. He feels they’ve “made a pretty good amount” (33). They consider how much more they could have made if they had wasted less lemonade. Scott tells Evan to make more lemonade, and even though Evan feels frustrated by Scott’s selfishness, he goes to the house and makes grape juice, as it’s all he has.

When Evan returns with the grape juice, Scott has finished the lemonade. They argue again about money, then realize that no one has come to their stand.
