B - Total number of Badges
N - Number of students

Translating the text into an equation, we get:

1/6 B =5*(5/6B)/(N-1)

N-1=25, N= 26 Answer B

We can let the total number of badges = n and the total number of students = q. Since one student gets 1/6 of the badges, the remaining students get 5n/6 of the badges. Thus the average number of badges the others got = (5n/6)/(q - 1), and we have:

(1/6)(n) = 5((5n/6)/(q - 1))

(1/6)n(q - 1) = 5(5n/6)

(q - 1)/6 = 25/6

q - 1= 25

q = 26

Answer: B
