Quizplus · Accepted Answer

The percentage change in the value of exports from 2009 to 2013 is calculated using the formula: [(Value in 2013 - Value in 2009) / Value in 2009] * 100. Assuming the index number for 2009 is 100, and the index number for 2013 is 190.6, the percentage change is [(190.6 - 100) / 100] * 100 = 90.6%.
