The rate of a country's per capita sales of bottled water for the period 2007-2014 could be approximated by s(t) = 0.22t-t + 24 gallons per year (0 t 7), where t is time in years since the start of 2007. Use a Riemann sum with n = 5 to estimate the total country's per capita sales of bottled water from the start of 2008 to the start of 2012. (Use a left Riemann sum to find your answer. Round your answer to the nearest gallon.) gal
