<gadget id="calculator">9*12</gadget>
<output>108</output>
108 five-minute intervals, thus total of 108*50 tickets were sold.   Say x student and 3x regular tickets were sold, then x+3x=108*50 --&gt; x=27*50 and 3x=3*(27*50)=27*150.   Therefore, the total revenue from ticket sales that day was 27*50*6+27*150*10=$48,600.   Answer: $48600.
