Final answer:
To calculate the nominal GDP, we multiply the real GDP by the price index. In this case, the price index is 112. So, if the real GDP is $3,668 billion, the approximate nominal GDP in that year would be $4,108 billion.
Step-by-step explanation:
To calculate the nominal GDP, we multiply the real GDP by the price index. In this case, the price index is 112. So, if the real GDP is $3,668 billion, the nominal GDP would be:
Nominal GDP = Real GDP × Price Index/100
Nominal GDP = $3,668 billion × 112/100
Nominal GDP = $4,108 billion
Therefore, the approximate nominal GDP in that year would be $4,108 billion.
