CPI (Consumer Price Index) is a measure of changes in prices paid by consumers for goods and services. It is used to estimate the changes in prices.
Therefore;
Change in prices = (CPI in current year - CPI in base year)/CPI in base year
Substituting for the values given in the current problem
Changes in prices = (108-100)/100 = 8/100 = 0.08 or 8%.
This shows that prices increased by 8% in the current year compared to the base year.
