please fully explain

What did Milton Friedman mean by saying that "inflation is always and everywhere a monetary phenomenon"? Inflation only affects those who hold money, as savings or in the form of investments. Inflation is due to cash transactions, not transactions based on credit. O In any economy that uses money as a medium of exchange, there will always be some inflation. O Inflation is about rising prices, not about rising productivity. Inflation is caused by an increase in the money supply relative to the quantity of goods and services
