Answer
$\$711$
Work Step by Step
Dividing the value of imports by the population, then
\begin{array}{l}\require{cancel}
\dfrac{2.21\times10^{11}}{3.11\times10^8}
\\=
\dfrac{2.21}{3.11}\times\dfrac{10^{11}}{10^8}
\\=
0.71061093247588424437299035369775\times10^{11-8}
\\=
0.71061093247588424437299035369775\times10^{3}
\\=
710.61093247588424437299035369775
.\end{array}
Hence, the average value of imports per person, rounded to the nearest whole, number is $
\$711
.$
