According to the Association of American Railroads, Class I freight railroads are the line-haul freight railroads with 2006 operating revenue in excess of $346.8 million. Let F = F(t) denote the freight revenue in billions of dollars of Class I railroads in year t. In 2005, Class I railroads had a freight revenue of $44.5 billion. In 2007, the revenue was $52.9 billion. Calculate the average rate of change per year in F from 2005 to 2007. billion dollars per year Explain in practical terms what this means. O This is the value, in billions of dollars, by which the freight revenue for Class I railroads decreased, on average, over this two-year period. O This is the value, in billions of dollars, describing the average difference in freight revenue for Class I and Class II railroads. O This is the number of years, on average, it takes for the freight revenue for Class I railroads to decrease by 2 billion dollars. O This is the number of years, on average, it takes for the freight revenue for Class I railroads to increase by 2 billion dollars. O This is the value, in billions of dollars, by which the freight revenue for Class I railroads increased, on average each year, over this two-year period.
