Problems 69-72 require the following discussion. The consumer price index (CPI) indicates the relative change in price over time for a fixed basket of goods and services. It is a cost of living index that helps measure the effect of inflation on the cost of goods and services. The CPI uses the base period 1982-1984 for comparison (the CPI for this period is 100). The CPI for March 2015 was 236.12 . This means that $ 100 in the period 1982-1984 had the same purchasing power as $ 236.12 in March 2015. In general, if the rate of inflation averages r percent per annum over n years, then the CPI index after n years is C P I = C P I 0 ( 1 + r 100 ) n where C P I 0 is the CPI index at the beginning of the n -year period.

Solution Summary: The author explains that if the current CPI is 234.2 and the average annual inflation rate is 2.8 %, what will be the Consumer Price Index in 5 years?
Problems 69-72 require the following discussion. The
consumer price index (CPI)
indicates the relative change in price over time for a fixed basket of goods and services. It is a cost of living index that helps measure the effect of inflation on the cost of goods and services. The CPI uses the base period 1982-1984 for comparison (the CPI for this period is 100). The CPI for March 2015 was
. This means that
in the period 1982-1984 had the same purchasing power as
in March 2015. In general, if the rate of inflation averages
