We want to compare the increase in value of the stock portfolio represented by the S&P/TSX Composite Index during the 18-year period described in Problem 14 to the general increase in prices of goods and services during the same period. The CPI rose from 79.8 at the end of 1990 to 113.3 at the end of 2008. Calculate the percent increase in the value of the portfolio and the percent increase in the general price level during the decade.
