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? Give me reasons, before answering the question
First find the total distance the bushes need to cover: 16 feet / side * 3 sides = 48 feet. Then divide the total distance to fill by the distance each bush fills to find the number of bushes Alice needs to buy: 48 feet / 4 feet / bush = 12 bushes. So the final answer is 12.
