ther is 7 girls on a bus
each girl has 7 bookbags
each bookbags has 7 big cats
for every big cat there are 7 little cats
how many legs are on the bus

there is 42 legs not including the bookbags

hi anthony,
hint first. try figuring out separately how many girls, then how many big cats, and then how many little cats.
obviously each girl has 2 legs and each cat 4 legs.
i get a few more than 42 legs on the bus
i get 7 girls,
7x7bookbags=49 book bags
7 bc x 49 bbs= 343 big cats
7 Lc x 343 bc = 2401 little cats
so.....girls 7x2=14legs
343bcx4=1372 big cat legs
2401x4= 9604 little cat legs
14+1372+9604=10990 legs
