at the end of a year, the gross debt of a country stood at about $20 trillion. express this amount in dollars per person, assuming that the population of the country is about 299 million. the gross debt is about $ per person. (type a whole number. round to the nearest hundred as needed.)

at the end of a year, the gross debt of a country stood at about $20 trillion. express this amount in dollars per person, assuming that the population of the country is about 299 million. the gross debt is about $ per person. (type a whole number. round to the nearest hundred as needed.)

Answer

Explanation:

Step1: Convert trillion and million to standard form

1 trillion = $10^{12}$, 20 trillion = $20\times10^{12}=2\times 10^{13}$; 1 million = $10^{6}$, 299 million = $299\times10^{6}=2.99\times 10^{8}$

Step2: Calculate debt per - person

Debt per person = $\frac{\text{Total debt}}{\text{Population}}=\frac{2\times 10^{13}}{2.99\times 10^{8}}$ Using the rule of exponents $\frac{a^{m}}{a^{n}}=a^{m - n}$, we have $\frac{2\times 10^{13}}{2.99\times 10^{8}}=\frac{2}{2.99}\times10^{13 - 8}\approx0.669\times10^{5}=66900$

Step3: Round to the nearest hundred

66900 is already rounded to the nearest hundred.

Answer:

66900
