[(CPI this year - CPI in the base year) + CPI in the base year] x 100 When the CPI O A. rises slowly, the inflation rate is low O B. is constant, the inflation rate is negative O C. falls, the inflation rate is positive and low O D. rises slowly, the inflation rate is negative The CPI in 2013 was 233.0. The CPI in 2014 was 234.8. The inflation rate in 2014 was percent. > >> Answer to 1 decimal place. > >> If your answer is negative, include a minus sign.
