Final answer:
If real GDP grew by 2% and the inflation rate was 2%, then nominal GDP grew by 0%.
Step-by-step explanation:
The growth rate of real GDP is equal to the growth rate in nominal GDP minus the inflation rate. In this case, since real GDP grew by 2% and the inflation rate was 2%, we can subtract the inflation rate from the growth rate in nominal GDP to find the growth rate in real GDP. 2% - 2% = 0%. Therefore, nominal GDP grew by 0% in this scenario.
