Faith Ferguson · Answer 1

953 billion

Step-by-step explanation:

Three years elapse between 2010 and 2013. The decay per year is 2.7%, meaning each year, the exports is 97.3% of that from the previous year (100% - 2.7%). Thus you can find the answer by doing 1.035 trillion times 97.3% to the power of 3 (the number of years). This results in approximately 953 billion.
