On April 22, 2017, the United States National Debt was at about 2.0 x 10^13dollars. The United States federal tax revenue was at about 3.3 x 10^12 dollars.After taxes were collected, how much of the national debt was still remaining?

Respuesta :

We need to compute 2.0 x 10^13 minus 3.3 x 10^12. The first number can be expressed as follows:

[tex]2.0\cdot10^{13}=2.0\cdot10\cdot10^{12}=20\cdot10^{12}[/tex]

Subtracting:

[tex]20\cdot10^{12}-3.3\cdot10^{12}=(20-3.3)\cdot10^{12}=16.7\cdot10^{12}=1.67\cdot10^{13}[/tex]

1.67 x 10^13 dollars still remains of the national debt.
