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 2008 to the start of 2010. (Round your answer to the nearest gallon.)
