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.
