Answer:$600
Explanation:
Number of van rides = Total number of visitors / Number of passengers per ride
Number of van rides = 216 / 9 = 24 van ridesIn each van ride, there are 5 adults and 4 children. Since children ride for free, the total cost per van ride is based only on the adult tickets.The total revenue for the zoo for all van rides can be calculated as follows:Total revenue = Total number of van rides * Revenue per van ride
Total revenue = 24 van rides * (5 adults per ride * $5 per adult)Total revenue = 24 * 5 * 5 = $600. Therefore, the zoo made $600 on rides to the zoo on opening day.
