Good article, but I question the $7 number.
$214,795
Our back-of-the-envelope calculation on how much more basketball revenue the Bulls have gained through improved attendance. We get that number by adding last season’s reported figures for ticket sales and novelty/parking/concessions and dividing it by the total attendance. That equals $7 per fan. Multiply that by the overall increase in attendance (30,685 fans), and you get our good-faith guesstimate.
