Final answer:
The correct substitute for the book title 'Dow 36,000' is 'The Sum of the Share Prices of All 30 Dow Jones Members Will Triple.' This reflects the price-weighted nature of the Dow Jones Industrial Average, which is based on stock prices rather than market capitalization.
Step-by-step explanation:
In the context of the Dow Jones Industrial Average, when we say that the Dow 36,000 is achieved, it indicates that the average price of the stocks in the index has tripled considering it rose from a base of circa 12,000 as mentioned. Hence, the most accurate substitute for the title 'Dow 36,000' from the given options would be 'The Sum of the Share Prices of All 30 Dow Jones Members Will Triple' as this option directly references the collective price movement of the stocks that make up the Dow Jones Industrial Average.
