The following graph gives a country’s yearly Consumer Price Index (CPI). Fill in the annual inflation rates. Round the answers to two decimal places.

Year CPI Inflation
2011 88.1
2012 90.9 3.18%
2013 93.8 o1eY4lW145Q=%
2014 96.1 YvW593U9Gcs=%

The inflation rate is the yearly percentage change in the Consumer Price Index. The formula for percentage changes is (CPI2 - CPI1) / CPI1 x 100%. For example, (90.9 - 88.1) / 88.1 x 100% = 3.18%. You could replace the numbers in this feedback with the actual numbers from the two columns, and repeat for each one.
