Just think of this: what has legs in that list of stuff in the bus? And many legs does each thing have.
OK is the irrelevant info the 7 small cats because it doesn't say they are in the bus nor the back packs? Or is it that the girls didn't bring the back packs?
All ways I thought of the problem are:
1) assuming all are in the bus...
for each girl there are 7 backpacks inside each are 7 big cats and 49 little cats then multiply by 4 legs then multiply by 7 since there are 7 girls then add two legs per 7 girls .
that would be 2401 cats X 4 legs 9,604 legs for each girl and x 7 for 7 girls + 14 legs for the total legs of all 7 girls.
I got 67242 legs in the bus
2) if the little cats are not on the bus then
it's just 7 big cats x 7 back packs x7 girls x 4 legs + 14 girl's legs. = 1386
7 girls x 7 backpacks X 7 cats per backpack so there are 343 cats then 343 cats + 14
1,386
Here are various answers I got and checked and they were not counted as correct.
