Zimbabwe's Descent into Economic Chaos During the Late 1990s and Early

Zimbabwe's descent into economic chaos during the late 1990s and early 2000s resulted in hyperinflation. By August of 2008, the monthly inflation rate stood at 839%! Retailers were increasing their prices more than once each day. The government had to issue currency in ever rising denominations-the highest denomination note circulating in August 2008 was for $100 billion ($100,000,000,000) Zimbabwean dollars!
a. Consider a loaf of bread with a price of $4 at the beginning of a month. With an inflation rate of 839% per month, what would the loaf's price be at the end of a month in order to "keep pace" with inflation?
b. In the scenario in part (a), what percentage of its purchasing power did a fixed nominal amount of currency retain at the end of the month?
c. What daily per cent price increase, compounded over a 30-day month, would result in an 839% overall price increase during the month?
d. Consider a piece of candy priced at just one cent ($0.01) at the beginning of a year. If inflation continued at the rate of 839% per month for an entire year, what would be the inflation-adjusted price of the candy at the end of the year?
