1. The problem statement, all variables and given/known data Bottled water consumption was reported to be 21 gal per person in the United States in 2002. The last census reported 2.9 x 10^8 people in the U.S. A. What is the total estimated bottled water consumption in the U.S.? B. If the per capita consumption of bottled water has increased 20% in the last 10 years, what was the per capita consumption 10 years ago? 3. The attempt at a solution A. 290,000,000 (or 2.9x10^8) x 21 gal = 6,090,000,000 (or 6.09x10^9) B. 20% of 21 gallons is 4.2 gallons. Do I add or subtract that from the 21 gal? How do I figure what the per capita consumption was 10 years ago?
