2022 were $70,021,” where “consumer units include families, single persons living
alone or sharing a household with others but who are financially independent, or two or more
persons living together who share expenses.”
a. “The average American lives on $𝐷𝐷 per day” is a common type of statistic used (not just
about Americans either). Using the information above, determine a reasonable amount
that could represent 𝐷𝐷 in this statistic. Be sure to explain your reasoning.Using your average dollar amount per day for an American, for how many days could an
American live on one trillion dollars? How many years is that? Decades? Centuries?
Millennium?

To answer this question, we need to break it down into parts.

### Part 1: Determining the average amount of money spent per day by an American

We know that the **annual** expenditure for a typical "consumer unit" in 2022 was **$70,021**. To calculate how much this represents per day, we can divide the annual amount by the number of days in a year (365 days):

\[
D = \frac{70,021}{365} \approx 191.84
\]

Thus, the average American consumer unit spends about **$191.84 per day**.

### Part 2: How long can an American live on one trillion dollars?

Now, let's calculate how many days an American could live on **one trillion dollars** (which is $1,000,000,000,000) based on the daily expenditure we just calculated.

To find out how many days they could live on one trillion dollars, we divide one trillion dollars by the daily expenditure:

\[
\text{Days} = \frac{1,000,000,000,000}{191.84} \approx 5,211,223,886.5 \text{ days}
\]

Thus, an American could live for about **5.21 billion days** on one trillion dollars.

### Part 3: Converting days into years, decades, centuries, and millennia

Now let's convert these days into various larger units of time:

#### a. Years
To convert days into years, divide by the number of days in a year (365):

\[
\text{Years} = \frac{5,211,223,886.5}{365} \approx 14,272,399.7 \text{ years}
\]

So, they could live for about **14.27 million years**.

#### b. Decades
To find out how many decades that is, divide the number of years by 10:

\[
\text{Decades} = \frac{14,272,399.7}{10} \approx 1,427,239.97 \text{ decades}
\]

That’s about **1.43 million decades**.

#### c. Centuries
To find out how many centuries that is, divide the number of years by 100:

\[
\text{Centuries} = \frac{14,272,399.7}{100} \approx 142,724 \text{ centuries}
\]

That’s about **142,724 centuries**.

#### d. Millennia
To find out how many millennia that is, divide the number of years by 1,000:

\[
\text{Millennia} = \frac{14,272,399.7}{1000} \approx 14,272.4 \text{ millennia}
\]

That’s about **14,272 millennia**.

### Summary

- The average American spends **$191.84 per day**.
- One trillion dollars could last about **5.21 billion days**, which is roughly:
  - **14.27 million years**,
  - **1.43 million decades**,
  - **142,724 centuries**,
  - **14,272 millennia**.

Here are 5 related questions to expand this topic:

1. What are the effects of inflation on daily expenditure over time?
2. How does the daily expenditure differ across different countries or regions?
3. What would the average daily expenditure be for a family of four compared to a single person?
4. How does the cost of living affect these average figures in major U.S. cities?
5. What would happen if the spending increased by 5% each year—how would it change over a decade?

**Tip:** When calculating large amounts of money over time, always account for inflation to get a more accurate long-term perspective!
