A U.S.-owned automobile factory uses $50 million worth of materials produced in the U.S. and $10 million worth of material purchased from foreign countries to produce $100 million of automobiles. $70 million worth of these automobiles are purchased by U.S. consumers, $25 million are sold in foreign countries, and $5 million are added to inventory. How much of this production is included in U.S. GDP? By how much do these transactions alone affect U.S. net exports?
