The zoo sold 264 admission tickets on Monday. If 1/4 of the tickets sold were adult tickets, which cost $28 each, how much money did the zoo make from the sale of the CHILDREN'S tickets if they cost 3/4 the amount of adult tickets?

1 answer

If 1/4 of the tickets sold were adult tickets, then 1/4*264 = <<1/4*264=66>>66 tickets were adult tickets.
If 1/4 of the tickets were adult tickets, then 1-1/4 = 3/4 of the tickets were children's tickets.
The total number of children's tickets sold is 3/4*264 = <<3/4*264=198>>198
If an adult ticket cost $28, the cost of a kids' ticket was 3/4*28 = <<3/4*28=21>>21 dollars.
The zoo made 198*$21 = $<<198*21=4158>>4158 from the sale of children's tickets. Answer: \boxed{4158}.
