HardSolution
Option E is the correct answer.
Option Analysis
From 9:00 in the morning to 5:55 in the afternoon, inclusive there are 9*12=108 five-minute intervals, thus a total of 108*30 tickets were sold.
Say x student and 3x regular tickets were sold, then x+3x=108*30 –> x=27*30 and
3x=3*(27*30)=27*90.
Therefore, the total revenue from ticket sales that day was 27*30*6+27*90*10=$29,160.
