One outdoor Rolling Stones show should bring 63750 individuals for a gross of $2.55 million. The promoter guarantees $1.40 million to the Rolling Stones. In addition, 20% of gross goes to the stadium in which the performance is staged. Add another $344000 for other expenses such as ticket takers, parking attendants, advertising, and so on. The promoter also shares in sales of T-shirts and memorabilia for which the promoter will net over $7 million during the tour. How much ticket revenue would the Rolling Stones promoter need to break even on a single concert, ignoring T-shirts and memorabilia?
