Final answer:
To calculate the inflation rate, divide the percentage increase in nominal GDP by the percentage increase in real GDP and multiply by 100. In this case, the inflation rate is 83.3%.
Step-by-step explanation:
To calculate the inflation rate, we need to compare the percentage increase in nominal GDP with the percentage increase in real GDP.
In this case, nominal GDP rose by $100 ($700 - $600) and real GDP rose by $30 ($530 - $500). Therefore, the inflation rate can be calculated as the percentage increase in nominal GDP divided by the percentage increase in real GDP, multiplied by 100.
Inflation rate = ($100/$600) / ($30/$500) x 100 = 83.3%.
