Final answer:
Based on the ratio of 225 branches for 75 wreaths, the florist would use 75 branches for 25 wreaths, following the ratio of 3 branches per wreath. The correct answer is option b) 75 branches.
Step-by-step explanation:
The student is asking how many branches of winterberry a florist would use to make 25 wreaths if 75 wreaths require 225 branches. To solve this, we will use a simple ratio based on the given information. If 75 wreaths require 225 branches, then we have a ratio of 225 branches to 75 wreaths, which can be simplified to 3 branches per wreath (225 ÷ 75 = 3).
To find the number of branches needed for 25 wreaths, we multiply the number of wreaths by the branches per wreath ratio (25 wreaths × 3 branches/wreath). Therefore, the calculation will be: 25 × 3 = 75 branches. The correct answer is that the florist would use 75 branches for 25 wreaths, which corresponds to option b).
