Answer: Raises the CPI and reduces real income.
Step-by-step explanation:
Inflation is a sustained rise in the general price level of the goods and services in an economy during a particular period. It is usually expressed as a percentage. Inflation leads to a reduction in the purchasing power of a country's currency.
Real income reduces because a rise in the price level with nominal income constant reduces the purchasing power of money. People holding real assets are better off than people who are holding cash.
