Answer:
The correct option is d. $400 billion.
Step-by-step explanation:
The question is asking for the 2010 GDP in terms of 2000 dollars. We know that the price index was 100 in the year 2000 and 120 in the year 2010. We also know that the GDP in 2010, based on 2010 prices, is $480 billion.
Hence, all we need to do is convert the 2010 prices into 2000 prices, and apply the new prices on the 2010 GDP figure. This can be done using the following formula:
(100/120) x $480 billion = $400 billion
Therefore, the answer is $400 billion.
