Answer 1

`(1)1.8X10^(13)\\(2)3.2X10^8\\(3)5.625X10^4`

Explanation:

1. Federal Debt=18 trillion dollars.

=18,000,000,000,000

`=1.8X10^{13`

2. Population =320 million people.

=320,000,000

`=3.2X10^8`

3. Federal Debt Per Capita

Debt Per Capita =Debt/Population

Therefore:

Federal Debt Per Capita

`=(1.8X10^(13))/(3.2X10^8)\\=0.5625X10^(13-8)\\=0.5625X10^5\\=5.625X10^4`
