Answer: 36.62 %
Explanation:
Given: Between 2000 and 2013, CPI in first period = 169.3
CPI in second period = 231.3
The average annual rate of inflation over the period = [tex]\dfrac{\text{ CPI in second period - CPI in first period}}{\text{CPI in first period}}\times100\%[/tex]
[tex]=\dfrac{231.3-169.3}{169.3}\times100=36.62\%[/tex]
Hence, the average annual rate of inflation over the period was =36.62%
