Finding the Average Rate of Inflation 107 4.10 Finding the Average Rate of Inflation 00wwwww Consider the graph, which gives the rate of inflation (in percent 400! per year) in a country with economic difficulties for the years indicated. 200 2005 2006 2007 2008 Inflation rate Problems 1. What was the average rate of inflation for the year 2006? 2. How much money would it take at the end of 2008 to have the same buying power as $100 at the beginning of 2005? 3. In a different country, the rate of inflation t years after 2006 is 4% times . (a) What is the average rate of inflation for this country from 2006 to 2013? (b) Draw a graph of the rate of inflation versus time and indicate on the graph what the average is. From Calewlus, an Active Approach with Projects by Hilbert, Schwartz, Selizer, Maceli, Robinson.
