About 8 hours, unless your homework isn't done or you haven't studied for the next day's test.

To determine how long a teenager needs to sleep at night, we can refer to recommendations from sleep experts. It's important to note that individual sleep needs may vary slightly, but here's a general guideline:

1. The American Academy of Sleep Medicine recommends that teenagers (ages 13-18) get 8-10 hours of sleep per night.
2. The National Sleep Foundation suggests that most teenagers need 9-10 hours of sleep each night.

However, to answer your teacher's question and earn those extra points, we can take the average range from these recommendations, which is approximately 8.5 - 9.5 hours of sleep per night for a teenager.

When it comes to answering similar questions in the future, you can use reliable sources like sleep organizations, medical websites, or consult sleep experts. These sources often provide updated guidelines based on scientific studies and research.
