The rate of U.S. sales of bottled water for the period 2007-2014 could be approximated by s(t) = 0.08t^2 - 0.26t + 8.8 billion gallons per year (0 ≤ t ≤ 7), where t is time in years since the start of 2007. (a) Estimate the average annual sales of bottled water over the period 2007-2009, to the nearest 100 million gallons per year. (b) Compute the 5-year moving average of s. (You need not simplify the answer.)

The rate of U.S. per capita sales of bottled water for the period 2007-2014 can be approximated by: s(t) = 0.25t^2 - t + 29 gallons per year Where t is time in years since the start of 2007. Find the total per capita bottled water sales as a function of the years since 2007 if per capita water bottle sales in 2010 was 100 gallons.

The rate of U.S. per capita sales of bottled water for the period 2007–2014 could be approximated by s(t) = 0.25t2 − t + 29 gallons per year (0 ≤ t ≤ 7), where t is time in years since the start of 2007.† Use a definite integral to estimate the total U.S. per capita sales of bottled water from the start of 2009 to the start of 2011. (Round your answer to the nearest gallon.) =________________gallon
