Question

7 kids on a bus with 1 driver each kid has 7backpacks inside each backpack are 7 cats for every cat their are 7kittens how many legs are on the bus

Answer 1

7^3*4+ 8*2 ( assuming every kitten, cat, kid and driver have no physical disabilities like legs missing:)

1372+16=1388 legs

Answer 2

7 kids + 1 bus driver = 8 people x 2 legs each = 16 legs

7 kids x 7 backpacks = 49 back packs.

Each backpack has 7 cats. 49 backpacks x 7 cats each = 343 cats x 4 legs each = 1372 legs.

343 cats x 7 kittens = 2401 kittens x 4 legs each = 9604 legs.

Total legs: 9604 + 1372 + 16 = 10,992 legs.
