B: For the Manager, their average income in 30 years is $2,592,000

C: The difference in both their earnings is $1,690,200

The annual expenditure of the US federal government is approximately 4 44 trillion dollars. If a one dollar bill is 0 . 0 0 0 1
kaheart [24]

Answer:

<em>A stack of 4 trillion one dollar bills will be  4\times 10^8 meters.</em>

Step-by-step explanation:

The annual expenditure of the US federal government is approximately 4 trillion dollars.

We know,  1 trillion dollars = 10¹² dollars.

So,  4 trillion dollars =(4\times 10^1^2) dollars.

Each one dollar bill is 0.0001 meters thick.

So, the total height of the stack of 4 trillion one dollar bills will be.....

[0.0001\times(4\times 10^1^2)]meters\\ \\ =[10^-^4\times(4\times 10^1^2)]meters\\ \\ =(4\times 10^8) meters
