# Step-by-Step Solution
Let's solve each part step by step:
---
## 1. Calculate GDP Using the Expenditure Approach
**Expenditure Approach Formula:**
\[ \text{GDP} = C + I + G + (X - M) \]
Where:
- \( C \) = Personal consumption expenditures = **400**
- \( I \) = Gross private domestic investment = **110**
- \( G \) = Government spending = **140**
- \( X \) = Exports = **55**
- \( M \) = Imports = **40**
**Plug in the values:**
\[
\text{GDP} = 400 + 110 + 140 + (55 - 40)
\]
\[
\text{GDP} = 400 + 110 + 140 + 15
\]
\[
\text{GDP} = 665 \text{ billion}
\]
---
## 2. Calculate National Income (NI)
**National Income Formula:**
\[
\text{NI} = \text{Employee compensation} + \text{Corporate profits and FICA contributions} + \text{Rental income} + \text{Net interest} + \text{Proprietors' income}
\]
Plug in the given values:
- Employee compensation = **450**
- Corporate profits and FICA contributions = **100**
- Rental income = **20**
- Net interest = **25**
- Proprietors' income = **15**
\[
\text{NI} = 450 + 100 + 20 + 25 + 15 = 610 \text{ billion}
\]
---
## 3. Calculate Personal Income (PI)
**Personal Income Formula:**
\[
\text{PI} = \text{National Income}
- \text{Corporate profits and FICA contributions}
- \text{Social Security contributions (not given, so skip)}
- \text{Taxes on production and imports (Indirect business taxes)}
+ \text{Transfer payments and other income}
\]
From the data:
- National Income = **610**
- Corporate profits and FICA contributions = **100**
- Indirect business taxes = **25**
- Transfer payments and other income = **55**
\[
\text{PI} = 610 - 100 - 25 + 55
\]
\[
\text{PI} = 610 - 125 + 55
\]
\[
\text{PI} = 485 + 55 = 540 \text{ billion}
\]
---
## 4. Calculate Disposable Personal Income (DPI)
**Disposable Personal Income Formula:**
\[
\text{DPI} = \text{Personal Income} - \text{Personal taxes}
\]
- Personal Income = **540**
- Personal taxes = **120**
\[
\text{DPI} = 540 - 120 = 420 \text{ billion}
\]

## **Final Answers (in billions of dollars):**
| | Billions of Dollars |
|------------------------|--------------------|
| **GDP** | 665 |
| **National Income** | 610 |
| **Personal Income** | 540 |
| **Disposable Personal Income** | 420 |

### **Summary Table**
| GDP | National Income | Personal Income | Disposable Personal Income |
|-----|----------------|----------------|---------------------------|
| 665 | 610 | 540 | 420 |
---
**Explanation:**
- **GDP** is found using the expenditure approach.
- **National Income** sums up all incomes earned by citizens and businesses.
- **Personal Income** adjusts national income by subtracting indirect taxes and corporate profits (not paid to individuals) and adding transfer payments.
- **Disposable Personal Income** is what individuals actually have to spend after paying personal taxes.
If you need any step explained further, let me know!
Question:
Short answer: **The first answer is correct.**
GDP = **665**, National Income = **610**, Personal Income = **565**, Disposable Personal Income = **445** (all in billions).
Why — step-by-step and where the second solution went wrong:
1. **GDP (expenditure approach)**
$$
GDP = C + I + G + (X-M) = 400 + 110 + 140 + (55-40) = 665.
$$
(Both solutions got this right.)
2. **National Income (NI)**
NI can be obtained from GDP by removing depreciation and indirect business taxes:
$$
NI = GDP - \text{Depreciation} - \text{Indirect business taxes} = 665 - 30 - 25 = 610.
$$
Or sum the factor incomes given: $450+20+25+15+100 = 610.$ (Both agree.)
3. **Personal Income (PI) — correct method**
Personal income is the income *received by households*. The clearest, unambiguous way with the given data is to add the incomes that actually go to households plus transfer payments:
$$
PI = \text{Employee comp} + \text{Rental} + \text{Net interest} + \text{Proprietors' income} + \text{Transfer payments}
$$
$$
PI = 450 + 20 + 25 + 15 + 55 = 565.
$$
(That matches the first answer.)
**Why the second solution’s PI = 540 is wrong:** it subtracts **indirect business taxes (25)** again from NI when forming personal income. But NI was already computed *after* subtracting indirect business taxes. So subtracting them a second time double-counts that deduction. In short: you should **not** subtract indirect business taxes again when going from NI → PI.
4. **Disposable Personal Income (DPI)**
$$
DPI = PI - \text{Personal taxes} = 565 - 120 = 445.
$$
So the second solution’s PI = 540 and DPI = 420 are incorrect because of the extra subtraction of indirect business taxes (and the resulting misapplication of the conversion formula).
If you want, I can show the NI→PI conversion algebraically using the specific categories (so it’s clear which items get subtracted and which get added).

Question:
The **first (earlier) answer is correct**. The second answer is wrong because it double-counts the indirect business taxes. Short, clear reasoning below.
### Correct results (billions)
* **GDP** = **665**
* **National Income (NI)** = **610**
* **Personal Income (PI)** = **565**
* **Disposable Personal Income (DPI)** = **445**
### Why — step by step and where the other solution erred
1. **GDP (expenditure):**
$$
GDP = C + I + G + (X-M) = 400 + 110 + 140 + (55-40) = 665.
$$
2. **National Income:**
You used GDP minus depreciation and indirect business taxes (this is correct in the way you computed NI):
$$
NI = GDP - \text{Depreciation} - \text{Indirect business taxes} = 665 - 30 - 25 = 610.
$$
(This also matches summing the factor incomes: $450+100+20+25+15 = 610$.)
3. **Personal Income (correct calculation):**
Personal income = income actually **received by households**. The easiest, unambiguous sum from the data is
$$
PI = \text{Employee comp} + \text{Rental} + \text{Net interest} + \text{Proprietors' income} + \text{Transfer payments}
$$
$$
PI = 450 + 20 + 25 + 15 + 55 = 565.
$$
Equivalent algebra starting from NI:
$$
PI = NI - \text{Corporate profits} + \text{Transfer payments}
$$
because NI includes corporate profits (which are not household income). That gives
$$
PI = 610 - 100 + 55 = 565.
$$
**Error in the second solution:** it used $PI = NI - 100 - 25 + 55$. The extra “$-25$” subtracts indirect business taxes again — but those were already removed when you computed NI = 610. So the second solution double-subtracts indirect business taxes, producing the incorrect PI = 540.
4. **Disposable Personal Income:**
$$
DPI = PI - \text{Personal taxes} = 565 - 120 = 445.
$$
If you want, I can show the two algebraic routes (sum of household receipts vs. NI adjustments) side-by-side to make the bookkeeping crystal clear.

### Summary
- **GDP** is calculated using the expenditure approach.
- **National Income** represents the total income earned by factors of production.
- **Personal Income** adjusts National Income by removing corporate profits and indirect taxes while adding transfer payments.
- **Disposable Personal Income** is the income available to households after personal taxes.
### Explanation of Errors in Second Solution
1. **GDP Calculation:** Both solutions correctly calculated GDP as \(665\) billion.
2. **National Income Calculation:** Both solutions calculated National Income as \(610\) billion correctly.
3. **Personal Income Calculation:** The second solution incorrectly subtracted indirect business taxes again from National Income, leading to \(540\) billion instead of the correct \(565\) billion. The correct calculation should only subtract corporate profits and add transfer payments.
4. **Disposable Personal Income Calculation:** The second solution arrived at \(420\) billion, which is correct based on the incorrect \(540\) billion for Personal Income.
**Final Correct Values:**
- **GDP:** \(665\) billion
- **National Income:** \(610\) billion
- **Personal Income:** \(565\) billion
- **Disposable Personal Income:** \(445\) billion
