Calculating the average cost of a concert—complete with overhead of auditorium use, administration, promotion and concert production costs—at $24,000, with box office average income of $12,750, divided by an average concert length of 90 minutes, that comes to $125 that must be raised per minute of music.
In order to keep the music going, we must raise $125 for every Minute of Music the Abilene Philharmonic performs.
