7 LITTLE CATS x 4 LEGS = 28

28 X 7 = 196 LITTLE CATS LEGS

7 BIG CATS X 4 LEGS = 28

7 GIRLS X 2 LEGS = 14

BUS DRIVER HAS 2 LEGS

196 + 28 + 14 + 2 = 240

I interpreted this question differently than Tim. Here's what I came up with:

7 girls x 2 legs each = 14 legs

If each girl has 7 backpacks and there are 7 big cats in each....49 backpacks x 7 cats=343 big cats. Then, there are 7 little cats for each big ...343x7=2401 little cats.

Total cats 2401+343=2744 total cats which have 4 legs each, so there are 10976 cat legs. Add this to the 14 girl legs and you get 10990 total legs. You might check to be sure this is what you need.
