The quantity demanded of a commodity is best described as which of the following?
- A flow expressed per unit of time at a given price
- A single isolated stock held by the seller
- A fixed lifetime total independent of price
- A value set only by the government regulator
Show answer and solution
Correct answer: A. A flow expressed per unit of time at a given price
1. Quantity demanded is always expressed at a given price.
2. It is a flow, not a single isolated purchase, so it is stated as 'so much per period of time'.
3. For example, one thousand dozens of oranges per day.
4. The option capturing both 'flow' and 'per unit of time at a given price' is correct.
