Ganezh [65]

Answer:

Higher

Step-by-step explanation:

1) In Macroeconomics, The core inflation rate does not include food and energy since these categories are way more volatile, due to oil and season matters.

Another Index, used by the Fed is the PCE, for the goods and services consumed by the US residents.
