Sum the units exported by companies A, B, and C for each year to find the combined totals. For 2011, the total is 1000 plus 1000 plus 3000, equaling 5000. For 2012, the total is 3000 plus 4000 plus 1000, equaling 8000. For 2013, the total is 4000 plus 3000 plus 3000, equaling 10000. For 2014, the total is 3000 plus 4000 plus 1000, equaling 8000. The matching combined totals occur in 2014 and 2012.
