It is estimated that in 2009 the United States consumed 18.69 million barrels of oil a day. A barrel of oil is 42 U.S. gallons. Assuming a U.S. population of 306 million, estimate per capita consumption in gallons, rounding each number.

I assume you are learnig about Dimensional analysis.....one more...

 (we aren't really here to do your homework.....we are here to help YOU do YOUR homework....i.e. "learn")

 

18690000 bbl/day x 42 gal/bbl  x 1/306 000 000 ppl = 2.565 gal/pp  each day

 

(Guest was correct...I had a typo and used 360 million people instead of the correct 306 million)
