There are 66 children and in all 33 dollars.
So, she can spend at most \(\displaystyle{d}{\frac{{{33}}}{{{6}}}}={d}{\frac{{{11}}}{{{2}}}}={5.5}\) dollars on each child.
Thus, the answer is $ 5.50, or if it must be an integer $ 55.

Here’s an interesting challenge you can give to a friend. Hold a $1 (or larger!) bill by an upper corner. Have a friend prepare to pinch a lower corner, putting her fingers near but not touching the bill. Tell her to try to catch the bill when you drop it by simply closing her fingers. This seems like it should be easy, but it’s not. After she sees that you have released the bill, it will take her about 0.25 s to react and close her fingers-which is not fast enough to catch the bill. How much time does it take for the bill to fall beyond her grasp? The length of a bill is 16 cm.
