A country's Consumer Price Index (CPI) is a measure of the cost of living. The inflation rate is the annual relative rate of change of the CPI. Use the data in the following table to estimate the inflation rate for each of years 2007–2012.

Year 2007
CPI 202.077

Year 2008
CPI 211.03

Year 2009
CPI 211.132

Year 2010
CPI 216.696

Year 2011
CPI 220.637

Year 2012
CPI 210.938

To estimate the inflation rate for each year, you need to calculate the percentage change in the Consumer Price Index (CPI) from the previous year. You can use the following formula:

Inflation Rate = ((CPI2 - CPI1) / CPI1) * 100

Where:
- CPI1 is the CPI for the previous year.
- CPI2 is the CPI for the current year.

Let's calculate the inflation rate for each year using the given data:

For Year 2007 to Year 2008:
Inflation Rate = ((211.03 - 202.077) / 202.077) * 100
= (8.953 / 202.077) * 100
= 4.43%

For Year 2008 to Year 2009:
Inflation Rate = ((211.132 - 211.03) / 211.03) * 100
= (0.102 / 211.03) * 100
= 0.048%

For Year 2009 to Year 2010:
Inflation Rate = ((216.696 - 211.132) / 211.132) * 100
= (5.564 / 211.132) * 100
= 2.63%

For Year 2010 to Year 2011:
Inflation Rate = ((220.637 - 216.696) / 216.696) * 100
= (3.941 / 216.696) * 100
= 1.82%

For Year 2011 to Year 2012:
Inflation Rate = ((210.938 - 220.637) / 220.637) * 100
= (-9.699 / 220.637) * 100
= -4.39%

So, the estimated inflation rate for each year is as follows:
- Year 2007 to Year 2008: 4.43%
- Year 2008 to Year 2009: 0.048%
- Year 2009 to Year 2010: 2.63%
- Year 2010 to Year 2011: 1.82%
- Year 2011 to Year 2012: -4.39% (negative value indicates deflation)
