Final answer:
To find how many seventh graders are drama club members, multiply 35% (or 0.35) by the total number of club members, which is 40. The result is 14 members, which is answer choice (b).
Step-by-step explanation:
To calculate how many drama club members are in seventh grade, we need to apply the percentage given to the total number of members in the club. Since the club has 40 members and 35% of those are seventh graders, the calculation is as follows:
Number of seventh graders = 35% of 40 members
Number of seventh graders = 0.35 × 40
Number of seventh graders = 14
Therefore, there are 14 drama club members who are in seventh grade, which corresponds to answer choice (b).
