Answer: 6 songs will be on the final CD.
Step-by-step explanation:
The number of songs that the band expected to put on their next CD is 12.
The band writes and records 25% more songs than they expect to put on the CD. This means that the additional number of songs that the band recorded is
25/100 × 12 = 0.25 × 12 = 3
Therefore, after writing and recording, the number of song was
12 + 3 = 15
During the editing process, 60% of the songs are removed. It means that the number of songs that were removed is
60/100 × 15 = 0.6 × 15 = 9
Therefore, the number of songs that will be on the final CD is
15 - 9 = 6
