The symphonic choir and the jazz choir are recording songs for an album. The album can be no more than 72 minutes long. The jazz choir records 7 songs with an average of 3 minutes per songEach symphonic choir song is an average of 3.5 minutes long. What is the maximum number of songs the symphonic choir can record?

Let x represent the number of songs the symphonic choir can record.

The album can be no more than 72 minutes long. The jazz choir records 7 songs with an average of 3 minutes per song.

Each symphonic choir song is an average of 3.5 minutes long

Hence:

(7 song * 3 minute per song) + (x song * 3.5 minute per song) ≤ 72 minute

21 + 3.5x ≤ 72

3.5x ≤ 51

x ≤ 14.6

The maximum number of songs the symphonic choir can record is 14 songs.
