If the total amount is 900, then it is possible that the amount of students is 600, and the amount of adults is 300, because 600/300=2. Then, if we multiply 300 by eight, we get 2400. 5,600 minus 2,400 equals 3200, so the amount of money the students and children would pay would be $3,200. 400 students and 200 children or vice versa sorry running out of time
