One day each summer, Chandler earns money by having a lemonade stand in his neighborhood. He charges $0.50 per glass of lemonade, and he made a total of $24. How many glasses of lemonade did he sell?

To determine the number of glasses Chandler sold, the total amount of money made, $24, needs to be divided by the cost per glass, $0.50. So he sold $24 / $0.50/glass = <<24/0.50=48>>48 glasses of lemonade. Answer: \boxed{48}.
