Transcribed Image Text:5. Interest, inflation, and purchasing power
Suppose Frances is an avid reader and buys only mystery novels. Frances deposits $2,000 in a bank account that pays an annual nominal interest rate
of 15%. Assume this interest rate is fixed-that is, it won't change over time. At the time of her deposit, a mystery novel is priced at $20.00.
Initially, the purchasing power of Frances's $2,000 deposit is
mystery novels.
For each of the annual inflation rates given in the following table, first determine the new price of a mystery novel, assuming it rises at the rate of
inflation. Then enter the corresponding purchasing power of Frances's deposit after one year in the first row of the table for each inflation rate. Finally,
enter the value for the real interest rate at each of the given inflation rates.
Hint: Round your answers in the first row down to the nearest mystery novel. For example, if you find that the deposit will cover 20.7 mystery
novels, you would round the purchasing power down to 20 mystery novels under the assumption that Frances will not buy seven-tenths of a mystery
novel.
