Rainbow Harbor Cruises charges $16/adult and $8/child for a round-trip ticket. The records show that, on a certain weekend, 900 took the cruise on Saturday and 600 took the cruise on Sunday. The total receipts for Saturday were $12,800, and the total receipts for Sunday were $7,200. Determine how many adults and children took the cruise on Saturday and on Sunday.
