The percentage change in the value of exports of crude oil from 2012 to 2013 is calculated as follows:Percentage change = [(Value in 2013 - Value in 2012) / Value in 2012] x 100= [(110.96 - 102.8) / 102.8] x 100= [8.16 / 102.8] x 100= 0.0794 x 100= 7.94%Therefore, the percentage change in the value of exports of crude oil from 2012 to 2013 is 7.94%, which is closest to 8.0%.
