Question

Assume the top three sources of oil imports for the United States in the same year were Saudi Arabia, Mexico, and Canada. These top three countries accounted for 40% of oil imports. The United States imported 2% more from Saudi Arabia than they did from Mexico, and 1.9% more from Saudi Arabia than they did from Canada. What percentage of the United States oil imports was from each country? A. Saudi Arabia: 17.5%, Mexico: 15.5%, Canada: 7% B. Saudi Arabia: 18.2%, Mexico: 16.3%, Canada: 5.8% C. Saudi Arabia: 16.8%, Mexico: 14.9%, Canada: 8.3% D. Saudi Arabia: 15.7%, Mexico: 13.8%, Canada: 10.5%

Answer 1

The percentage of United States oil imports from each country is Saudi Arabia: 15.7%, Mexico: 13.8%, Canada: 10.5%.

Option (D) is true.

Explanation:

Let's assume the total oil imports to the United States in that year were 100 units.

According to the information given:

Saudi Arabia imported 2% more than Mexico, so if we assume the percentage of oil imports from Mexico is x, then the percentage from Saudi Arabia would be x + 2.

Saudi Arabia imported 1.9% more than Canada, so the percentage from Saudi Arabia would be x + 1.9, and the percentage from Canada would be x - 1.9.

Now, we know that the top three countries accounted for 40% of oil imports, which means the sum of their percentages should be 40.

Setting up the equation:

x + (x + 2) + (x - 1.9) = 40

Simplifying the equation:

3x + 0.1 = 40

3x = 39.9

x ≈ 13.3

Now, we can calculate the percentages for each country:

Saudi Arabia ≈ 13.3 + 2 ≈ 15.3%

Mexico ≈ 13.3%

Canada ≈ 13.3 - 1.9 ≈ 11.4%

Therefore,

Option (D) is true.
