Answer:
fiction books = 4
non fiction books = 8
non fiction books are twice fiction books.
Step-by-step explanation:
let number of fiction books be X so
non fiction books will be 12-X
12X + 25(12-X) = 248
12X -25X = -53
X = 4( fiction books)
12-4 = 8 (non fiction)
you didnt give much context but excluding breaks she might get it should be 24,400
450(x). x being weeks in a year (52)
Well there is 24 hours in a day so 24 - 15 = 9. So he spends 9 hours awake.
