Explanation Given: The amount of money U.S. consumers spend online for food (in billions) can be approximated by the function f ( x ) = .174 ( 1.318 ) x , where x = 11 corresponds to the year 2011. Calculation: Consider the function: f ( x ) = .174 ( 1.318 ) x Substitute 20 for f ( x ) to determine the value of x . .174 ( 1.318 ) x = 20 ( 1
