The consumer price index (CPI) indicates the relative change in price over time for a fixed basket of goods and service. In general if the rat of inflation averages r% over n years, then the CPI after n years is CPI=CPI (base 0) (1+(r/100))^n, where CPI(base 0) is the CPI index at the beginning of the n-years.

(a) the CPI was 151.5 for 1995 and 202.4 for 2003. Assuming that annual inflation remained constant for this time period, determine the average annual inflation rate.
a) the average annual inflation rate from 1995 to 2003 was approximately__%

(b) Using the inflation rate from part a in what year will the CPI reach 256?
b) the CPI will reach 256 in the year ________
