Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Alice is planting bushes around three sides of her yard. If each side is 16 feet long, and each bush fills 4 feet, how many bushes does she need to buy?

### Response:
First find the total distance the bushes need to cover: 16 feet/side * 3 sides = <<16*3=48>>48 feet
Then divide the total distance to be covered by the distance each bush will fill: 48 feet / 4 feet/bush = <<48/4=12>>12 bushes
