Answer
$\$175$
Work Step by Step
The amount each citizen has to pay is:
\[\begin{align}
& \text{ Each citizen would pay}=\frac{\text{Total amount allocated}}{\text{Total population}} \\
& =\frac{\$53.6\times{{10}^{9}}}{307\times{{10}^{6}}}\\
& =\frac{\$536\times{{10}^{8}}}{307\times{{10}^{6}}}\\
&=\$1.7459\times{{10}^{8-6}}\\&=\$174.59\end{align}\]
Take approximate value as follows:
\[\begin{align}
& \text{ Each citizen would pay = }\$ 174\text{.59}\approx \$175\end{align}\]
Hence, the amount each citizen would pay is
$\approx\$175$
