Final answer:
From 1980 to 1990, European real GDP grew by 39%, but when adjusted for inflation, the real GDP growth was approximately 43%. This data does not cover the exact period of 1979-89 but provides a close approximation.
Step-by-step explanation:
The European average GDP growth from 1979-89 can be inferred by looking at the data we have for 1980-1990. During that time, real GDP grew by 39% from a base of 5,926.5 to 8,225.0. However, it is important to note that not all of this growth represents an actual increase in economic output; approximately 57% of this growth was due to inflation. Therefore, when adjusting for inflation, the actual growth in real GDP was about 43% over this ten-year period. While this data does not cover exactly the years 1979-89, it should provide a good approximation of the GDP growth during that time as the economic trends are unlikely to have shifted dramatically between 1979 and 1980.
