The school bought 720 books and distributed them to senior high schools and junior high schools.
If the lower grades get X copies, the middle grades get 2x+4 copies and the upper grades get 3x+8 copies.

x+2x+4+3x+8=720

8x+ 12=720

x= 1 18

So the lower grades get 1 18, the middle grades get 2× 1 18+4=240, and the upper grades get 3× 1 18+8=362.
