The rate of a country's sales of bottled water for the period
2007-2014could be approximated by
s(t)=0.02t^(2)-0.28t+8.4 billion gallons per year (0<=t<=7),where
tis time in years since the start of 2007. Use a Riemann sum with
n=5to estimate the total sales of bottled water in this country from the start of 2008 to the start of 2014 . (Round your answer to the nearest billion gallons. Use a left Riemann sum to find your answer. Round your answer to the nearest whole number.) HINT [See Example 2.] billion gallons
