The total number of children is:

So, we have:


Simplify

1st, get the amount 1% is of 122 by dividing 122/100, so 1.22. then find how many times 1.22 can go into 57. so 5700/122 is you get 46.7%.
The range is Max - Min = 299 - 0 = 299
Divide this range over 10 to get 299/10 = 29.9 which rounds to 30
We'll need about 30 intervals if we want intervals of width 10
Answer: D) 25 or more
