i havent read thru the answers so i dont know if im reposting someones answer but waht i got was.. 1582

we assume each girl has 2 legs and each cat has 4 legs.
7 girls = 14 legs
7 backpacks = no legs.
7 big cats in each backpack so... thats 49 cats so thas 196 legs.
for each big cat there are 7 little ones. so 49 * 7 = 343 cats which is 1372 legs
now 14 + 196 + 1372 = 1582 legs


BUT u said there are 7 girls on the bus right... which is probably on top of the bus... so there would be 0 legs IN the bus cuz everyone is on top... if you meant to say 7 girls in the bus the answer is 1582.
