What is the public debt for the economy?

A. [tex]$\$[/tex] 540[tex]$ billion

B. $[/tex]\[tex]$ 400$[/tex] billion

C. [tex]$\$[/tex] 580[tex]$ billion

D. $[/tex]\[tex]$ 460$[/tex] billion



Answer :

Let's go through the step-by-step solution to determine the public debt based on the given data.

We need to find the total public debt by summing up the amounts of each type of security listed.

Here are the amounts provided for each security:
- Treasury Bills: \[tex]$220 billion - Corporate Bonds: \$[/tex]140 billion
- Treasury Notes: \[tex]$80 billion - Corporate Stock: \$[/tex]200 billion
- US Savings Bonds: \[tex]$60 billion - Treasury Bonds: \$[/tex]100 billion

Next, we add these amounts together:

[tex]\[ 220 \text{ billion} + 140 \text{ billion} + 80 \text{ billion} + 200 \text{ billion} + 60 \text{ billion} + 100 \text{ billion} \][/tex]

Summing them step by step:
1. [tex]\(220 + 140 = 360\)[/tex]
2. [tex]\(360 + 80 = 440\)[/tex]
3. [tex]\(440 + 200 = 640\)[/tex]
4. [tex]\(640 + 60 = 700\)[/tex]
5. [tex]\(700 + 100 = 800\)[/tex]

So, the total public debt is:

[tex]\[ \$ 800 \text{ billion} \][/tex]

Given the answer choices:
- \[tex]$540 billion - \$[/tex]400 billion
- \[tex]$580 billion - \$[/tex]460 billion

The correct option is not listed among the choices. The total public debt, based on the amounts provided, is \$800 billion.
