A consumer price index (CPI) measures changes in the price level of market basket of consumer goods and services purchased by households.

The CPI is a statistical estimate constructed using the prices of a sample of representative items whose prices are collected periodically. 

price 1995 = cost 1980 x ( CPI 1995 / CPI 1980)

price 1995 = $ 2.70 x ( 152.4 / 82.4 )

price 1995 = $ 4.99 is
