If the inflation rate is 100j% per annum over a period of n years, what is the purchasing power of a dollar at the end of n years as a percentage of its purchasing power at the beginniing of that period. this is what I did:

The purchasing power of a dollar at the end of n years of 100% annual inflation is $1.100^-n or 1 and I know this must be set up inncorrectly. The dollar should be less but I don't think this is the right answer.

Thankx,

Keith
