### Instruction:
Hannah fills her kids' stockings with 4 candy canes, 2 beanie babies and 1 book. If she has 3 kids, how many stocking stuffers does she buy total?

### Response:
First find the total number of stocking stuffers one kid gets: 4 candy canes/kid + 2 beanie babies/kid + 1 book/kid = <<4+2+1=7>>7 stocking stuffers/kid
Then multiply the number of stocking stuffers per kid by the number of kids to find the total number: 7 stocking stuffers/kid * 3 kids = <<7*3=21>>21 stocking stuffers
