Let M = the number of males
The number of females on the council is 3 less than 3 times the number of males on the council
So, 3M - 3 = the number of females
The town’s economic development council has 21 members.
So, (# of males) + (# of females) = 21
We get: M + (3M - 3) = 21
Simplify: 4M - 3 = 21
So: 4M = 24
Solve: M = 6
Answer: B
