Answer:
The daily consumption rate per capita is equal to USA daily consumption divided by the population in 2010.
This give us 0.062 barrels of oil (19,148,000/309,000,000).
Step-by-step explanation:
The usage of barrels of oil is indicated in a daily total of 19,148,000 barrels.
The 2010 USA population is given as 309 million.
Therefore, to obtain the daily consumption of barrels of oil per person or the consumption rate per capita, the daily consumption is divided by the population.
Consumption rate per capita is the consumption per each head in the population.
This consumption rate per capita can be used to compare the consumption over time and with other countries with different population sizes. This rate also indicates how each individual citizen of the USA is affected by the consumption of oil.
It does not actually imply that each individual has or can consume such quantity of oil per day.
