The Consumer Price Index (CPI) provides a means of determining the purchasing power of the U.S. dollar from one year to the next. Using the period from 1982 to 1984 as a measure of $100.0,$ the CPI for selected years from 1995 through 2007 is shown in the table. To use the CPIto predict a price in a particular year, we set up a proportion and compare it with a known price in another year: $$\frac{\text { price in year } A}{\text { index in year } A}=\frac{\text { price in year } B}{\text { index
