there should be at least 100 adults and 50 students because if there are 100 hundred adults- that means there would be 1 student per 2 adults giving you 100 adults and 50 student equaling a total of 150 seats which is the max seats the theater can hold and that would raise
$2.00 x 100 = $200.00
$1.00 x 50 = $50.00
$200.00 + $50.00 = $250.00
$250.00 is the max amount of money the program can make and to make that $250.00--- 100 adults and 50 students would have to attend
