Suppose crude oil comprises 25% of U.S. imports from Canada, U.S. production is 500 million barrels of crude oil, U.S. consumption is 1.49 billion barrels of crude oil, and the United States only imports crude oil from Canada. If the world price is $80 per barrel and the United States imposes a 20% tariff on each barrel, what is the amount of government revenue collected in the United States if the United States imports 40% less from Canada as a result of the tariff?
