Answer:
10976
Step-by-step explanation:
First lets start off by finding out how many cats there are (not kittens).
There were 7 girls, with 7 bags each, which contained 7 cats.
That turns into 7^3 or 7 * 7 * 7
7^3 = 343 cats
343 cats * 4 legs = 1372 legs (keep this for later).
Now you must find out how many kittens there are.
343 cats with 7 kittens each = 343 * 7
2401 kittens * 4 legs = 9604 legs
Now you must bring in the legs of the cats and kittens and add them together.
1372 legs (cats) + 9604 legs (kittens) = 10976 legs (total)
