Activity: "Calculate how many cups of water each person in Albuquerque uses at home each day."
Note: Sometimes water is measured by"per capita" use. That means we measure how much water is used by homes, industry, businesses, hospitals, schools and so on. then we divide by how many people live in the city. This number is always higher. In Albuquerque, our per capita use in 2009 was 159 gallons per person per day.
