d) Running water continuously while brushing teeth can use 1 – 3 gallons of water per minute, depending on the flow rate of the faucet. The American Dental Association recommends brushing your teeth for 2 minutes, twice a day. If every resident of Chicago followed this recommendation, but ran the water continuously while brushing, then how much water is used each day just for teeth brushing? e) Fluoride is added to water to reduce cavities. In 2015, the U.S. Department of Health and Human Services recommended adding 0.7 mg of fluoride per liter of water. Given that 2.2 pounds = 1 kg and 1 gallon = 3.78 liters, then how many pounds of Fluoride is added to Chicago water each day? Recall that 1g = 1000 mg and that 1 kg = 1000 g.
