Ok, start one step at a time. 
There is 60 minutes in 1 hour. 
If 24 minutes go to commercials, that leaves 36 minutes. 
If 4 minutes go to news, that leaves 32 minutes. 
If 3 minutes go to weather, that leaves 29 minutes. 
If 2 minutes go to PSA;s, that leaves 27 minutes. 

This leaves a total of 27 minutes for music, is each song is 3 mintues in length that means there is time for 9 songs (27/3)
