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 song. Each symphonic choir song is
an average of 3.5 minutes long. What is the maximum number of songs the symphonic choir can record?

[72 min - ( 7 songs  x  3 min/song)] / 3.5 min/song  = ....... songs

 

(72 - (7 x3))/ 3.5 = ........   songs
