From data gathered in the period 2008β2012, the yearly value of U. S. exports can be modeled by the function E(x) = β228x3 + 2,252.8x2 β 6,098.5x + 11,425.8 where x is the number of years after 2008 and E(x) is the value of exports in billions of dollars. The yearly value of U. S. imports can be modeled by the function I(x) = β400.4x3 + 3,954.4x2 β 11,128.8x + 17,749.6 where x is the number of years after 2008 and I(x) is the value of imports in billions of dollars. Estimate the total value the U. S. imported and exported in 2011. Round to the nearest whole number. About billion dollars were imported and exported by the U. S. in 2011.
