Answer:1084
Step-by-step explanation:you take 126 x 9 and if the teachers are free you leave them out and you get ten dollars for every 25 students and 5 x 25 is 125 that means you take your answer from 126 x 9 and subtract 50 and it leaves you with 1084
24+32+30+28=114
114÷2 groups =57
57 kids in each group
Take 8/20 and multiply it by the number of minutes in an hour (60)
6/20 x 60/1
360/20
simplify. divide both numbers by the GCF, 20.
360/20 / 20/20
18/1
there are 18 minutes (1080 seconds) in 8/20 of a hour.
Your answer in simplest radical form would be 531441/64
