Answer
${{\$}} 150,819 $ (debt per capita)
Work Step by Step
Debt:
$r=0.064, P=17.5$ (trillion),
$t= 2030-2014=16, $
compounded $n=1$ times a year:
$A_{d}=P\displaystyle \cdot(1+\frac{r}{n})^{nt}=17.5(1+\frac{0.064}{1})^{16\cdot 1}\approx{{\$}} 53.454879 \times 10^{12}$
Population:
$A_{p}=357(1+\displaystyle \frac{0.007}{1})^{16\cdot 1}\approx 354.430258\times 10^{6}$
$\displaystyle \frac{A_{d}}{A_{p}}={{\$}} 150,819 $ (debt per capita)
