Explanation
To find the rate of change, we will have to identify the months
The table below shows the months required
We will find the change in the inflation by dividing by the change in inflation by the change in month
The rate of change from February and April will be
[tex]\begin{gathered} \frac{2.6-2.1}{3-1}=\frac{0.5}{2}=0.25 \\ \\ \end{gathered}[/tex]
The rate of change from February and April is 0.3% per month
The rate of change between July and October will be
[tex]\frac{1.8-2.2}{9-6}=\frac{-0.4\text{ \%}}{3}=-0.133\text{ \%}[/tex]
The rate of change between July and October will be - 0.1 % per month
