Answer:

B. 6

Step-by-step explanation:

The percussion section is a subset of the class band which is a subset of the sophomore class.

Given;

40% of the 300-member sophomore class is in the band. The percussion section is made up of 5% of these band members.

Number of members of sophomore class in band = 40% × 300

= 120

Percussion section members = 5% × 120

= 6 members

6 0

40% of 300 = 0.40(300) = 120 are in the band
5% of 120 = 0.05(120) = 6 are in percussion
