Answer:
Inflation = 9.5%
Explanation:
Inflation can be defined as the persistent general rise in the price of goods and services in an economy at a specific period of time.
Given the following data;
Nominal interest rate = 7 percent.
Real interest rate = -2.5 percent
Real interest rate = Nominal interest rate - Inflation
Inflation = Nominal interest - Real interest rate
Inflation = 7 - (-2.5)
Inflation = 9.5%
