Answer :

To determine how many stars are on an American flag, we need to understand the historical and current significance of the stars on the flag.

Each star on the American flag represents one of the states in the United States. As of today:

- The United States has a total of 50 states.
- Therefore, the American flag has 50 stars.

Each star symbolizes a state, and the pattern of the stars has been updated to reflect the admission of new states over time.

So the correct answer is:

50 (one for each state in the U.S.).
