Given:
The total amount of bananas consumed per year, T=5.72 million metric tons.
The number of people in US, N=300 million.
1 metric ton=1000 kg.
The amount of bananas consumed by a person is,
[tex]\begin{gathered} A=\frac{T}{N} \\ =\frac{5.72\text{ million metric ton}}{300\text{ milllion }} \\ =\frac{5.72}{300}metric\text{ ton} \end{gathered}[/tex]Since 1 metric ton=1000 kg,
[tex]\begin{gathered} A=\frac{5.72}{300}metric\text{ ton}\times\frac{1000\operatorname{kg}}{1\text{ metric ton}} \\ \cong19.07\text{ kg} \end{gathered}[/tex]Therefore, approximately 19.07 kg of bananas are consumed by a person per year.
