Final answer:
To find the national income in the given context, we use the formula provided in Chapter 19, which allows us to calculate the national income as $522 billion. However, it is unclear whether this calculation answers the student's question due to incomplete information.
Step-by-step explanation:
The question provided pertains to calculating the national income using data given in various economic scenarios. The answer to the question related to the value of national income is not present in the information supplied.
However, if we assume the question's context is from Chapter 19, we can calculate national income based on the data given in that scenario which states: GDP + Income receipts from the rest of the world - Income payments to the rest of the world - Depreciation = $560 + $10 - $8 - $40 which results in a national income of $522 billion. Otherwise, the answer might be different depending on additional information that could have been provided.
