To find the amount of debt per person in the country, we can divide the total debt by the population.
The total debt is given as \( 1.87 \times 10^{13} \), which is \( 18,700,000,000,000 \).
We will also use the population of 324 million, which is \( 324,000,000 \).
Now, we'll perform the calculation:
\[ \text{Debt per person} = \frac{\text{Total debt}}{\text{Population}} = \frac{1.87 \times 10^{13}}{324,000,000} \]
Calculating that:
\[ \text{Debt per person} = \frac{18,700,000,000,000}{324,000,000} \approx 57,787.65 \]
Thus, the debt per person in the country was approximately $57,787.65.
