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