Final answer:
Kathy will use half of the candy from each of the five 1-pound bags for her project, totaling 2.5 pounds of candy.
Step-by-step explanation:
Kathy has five 1 pound bags of different flavored candy, and she plans to use half of the candy from each bag in her class project. To find out how much candy she will use, we need to calculate half of each pound and then sum the totals.
Calculating half of one pound (which is 16 ounces) gives us 8 ounces or 0.5 pounds. Since there are five bags, we multiply 0.5 pounds by 5.
0.5 pounds/bag × 5 bags = 2.5 pounds
Therefore, Kathy will use 2.5 pounds of candy in her project, which means the correct answer is (b) 2.5 pounds.
