How much more sleep would you get in a week if you slept 8 ½ hours a night instead of 15/2 hours per night?

7 hours

Step-by-step explanation:

15/2 hours=7 1/2 hours

(15:2=7 1/2)

8 1/2 hours - 7 1/2 hours = 1 hour

(find the difference)

1 week = 7 days

1 hour * 7 days = 7 hours

(1 hour difference for one day, multiply 7 for a week)
