A museum sold admission tickets to a group of 30 people every 5 minutes from 9:00 in the morning to 5:55 in the afternoon, inclusive.The phrase in blue implies that each hour an additional batch of 30 tickets is sold at the following times:
X:00, X:05, X:10, X:15, X:20, X:25, X:30, X:35, X:40, X:45, X:50, X:55
Since 30 tickets are sold at each of the 12 times listed above, the number of tickets sold each hour = 30*12 = 360
The price of a regular admission ticket was $10 and the price of a student ticket was $6.
3 times as many regular admission tickets were sold as student tickets.For every $6 student ticket sold, three $10 regular tickets are sold.
Thus:
Average price for every 4 tickets sold \(= \frac{(1*6) + (3*10)}{4} = 9\) per ticket
What was the total revenue from ticket sales that day?
\(\frac{9-hours}{1} * \frac{360-tickets}{1-hour} * \frac{$9}{per-ticket} = 29160\)
