The price of a regular admission ticket was $10 and the price of a student ticket was $6. If on one day 3 times as many regular admission tickets were sold as student tickets, what was the total revenue from ticket sales that day?

96 five-minute intervals, thus total of 96*30 tickets were sold.   Say x student and 3x regular tickets were sold, then x+3x=96*30 --&gt; x=24*30 and 3x=3*(24*30)=24*90.   Therefore, the total revenue from ticket sales that day was 24*30*6+24*90*10=$25,920.   Answer: $25920.
