Question

about 70 million tons of paper are used in the UnitedStates. If the U.S. population is about 301.6 million people, how many kilograms of paper are used by the averatge U.S. citizen?

Answer 1

Answer : The amount of paper used by average United States citizen are, 210.47 kilograms.

Explanation : Given,

Total mass of paper used in the United States = 70 million tons

Total number of people in the United States = 301.6 million

First we have to calculate the amount of paper used by average United States citizen.

`\text{Amount of paper used}=\frac{\text{Total mass of paper used}}{\text{Total number of people}}`

`\text{Amount of paper used}=\frac{70\text{ million tons}}{301.6\text{million}}`

`\text{Amount of paper used}=0.232\text{ tons}`

Now we have to convert amount of paper from tons to kilogram.

Conversion used :

1 ton = 907.185 kg

As, 1 ton = 907.185 kg

So, 0.232 ton =
`(0.232ton)/(1ton)* 907.185kg=210.47kg`

Therefore, the amount of paper used by average United States citizen are, 210.47 kilograms.
