Final answer:
The Arctic National Wildlife Refuge (ANWR) would provide 0.3% (option c) of the U.S. annual oil consumption, calculated by dividing the 0.33 billion gallons of oil ANWR can supply by the 110 billion gallons the U.S. uses and then multiplying by 100.
Step-by-step explanation:
The student is asking what percent of the oil used per year in the U.S. would be provided by the Arctic National Wildlife Refuge (ANWR), given that ANWR would yield a projected peak amount of approximately 330 million gallons of oil a year and the U.S. uses roughly 110 billion gallons of oil in a year. To calculate this, we can use the formula for percentage:
Percent = (Part / Whole) × 100
First, we need to convert the values to the same unit of measurement. Since the U.S. consumption is given in billions, we'll convert the ANWR projection to billions as well:
- ANWR yield in billions of gallons = 330 million gallons / 1000 = 0.33 billion gallons
Then we can plug these values into the formula:
Percent = (0.33 billion / 110 billion) × 100
Percent = (0.003) × 100
Percent = 0.3%
So, the correct answer is c-0.3%, meaning ANWR would provide 0.3% of the oil used per year in the U.S.
