Final answer:
Real GDP is a measure of the total value of all final goods and services produced in an economy, taking into account the effects of inflation. Without the nominal GDP figure for 2018, it is not possible to determine the real GDP in that year.
Step-by-step explanation:
Real GDP stands for Real Gross Domestic Product, which measures the total value of all final goods and services produced in an economy. It takes into account the effects of inflation by adjusting the nominal GDP. In order to calculate the real GDP in a particular year, we need to use a base year as a reference point.
Since the question asks to use 2018 as the base year, the real GDP in 2018 would be equal to the nominal GDP of that year. However, the given information does not provide the nominal GDP for 2018. Without the nominal GDP figure, it is not possible to determine the real GDP in 2018.
