Table 1.11 shows the CPI with the index set equal to 100 in 2008. Suppose that we redo the CPI so that the index equals 100 in 1958; if so, what is the value of the CPI in 2008? What is the percentage increase in the CPI between 1958 and 2008 if we use the CPI with the index equal to 100 in 2008? If we use the CPI with the index equal to 100 in 1958?
