Inflation Problems 57-62 require the following discussion. Inflation is a term used to describe the erosion of the purchasing power of money. For example, if the annual inflation rate is 3 % , then $ 1000 worth of purchasing power now will have only $ 970 worth of purchasing power in 1 year because 3 % of the original $ 1000 ( 0.03 × 1000 = 30 ) has been eroded due to inflation. In general, if the rate of inflation averages r per annum over n years, the amount A that $ P will purchase after n years is A = P · ( 1 − r ) n where r is expressed as a decimal. Inflation If the average inflation rate is 2 % , how long is it until purchasing power is cut in half?
