Question

A band expects to put 12 songs on their next CD. The band writes and records 25% more songs than they expect to put on the CD. During the editing process, 20% of the songs are removed. How many songs will there be on the final CD?

Answer 1

The band writes and records 15 songs after planning for 12, accounting for a 25% increase. After removing 20% of the songs during editing, which is 3 songs, they are left with 12 songs for the final CD.

Step-by-step explanation:

The band initially plans to put 12 songs on their CD. To find the number of songs written and recorded, which is 25% more than they expect, we calculate 12 songs + (25% of 12 songs). This gives us 12 + (0.25 × 12) = 12 + 3 = 15 songs written and recorded. Next, we consider that 20% of these songs are removed during the editing process. Therefore, we find 20% of 15 songs, which is 0.20 × 15 = 3 songs removed.

Subtracting the removed songs from the total number of recorded songs, we get 15 - 3 = 12 songs that remain. Consequently, there will be 12 songs on the final CD.
