Which of the following is true about the value of money?

The correct answer is: "it varies inversely with the price level." Money is a means of exchange and its value is determined by its purchasing power, which is the amount of goods and services it can buy. The price level, on the other hand, is the average level of prices of goods and services in an economy. Inflation, which is an increase in the price level, reduces the value of money, because it reduces the amount of goods and services that can be purchased with a given amount of money. Conversely, deflation, which is a decrease in the price level, increases the value of money, because it increases the amount of goods and services that can be purchased with a given amount of money. Therefore, the value of money varies inversely with the price level.
