Answer: 1.3%
Step-by-step explanation:
Inflation refers to general increase in prices in a given economy in a given period. Given the variables available, the best formula to use would be the Economic growth formula;
Economic Growth = %Δ Nominal GDP – %ΔPrices – %ΔPopulation
0.3 = 2.0 - %ΔPrices - 0.4
%ΔPrices = 2.0 - 0.4 - 0.3
%ΔPrices = 1.3
Inflation rose by 1.3%
