To calculate inflation, we need to find the percentage increase in CPI from one year to another. In this case, the CPI has increased from 180 to 189, which is a difference of 9. To find the percentage increase, we divide the difference by the starting value and multiply by 100. So, (9/180) x 100 = 5%. Therefore, inflation during 2011 was 5%.
