Question
A school district is forming a committee to discuss plans for the construction of a new high school. Of those invited to join the committee, 15% are parents of students, 45% are teachers from the current high school, 25% are school and district administrators, and the remaining 6 individuals are students. How many more teachers were invited to join the committee than school and district administrators?
The correct answer is: 8
Let x represent the total number of people in the community
0.15x + 0.45x + 0.25x + 6 = x
0.85x + 6 = x
x – 0.85x – 6
0.15x = 6
x = 0.25 
40
x = 0.45 40 = 8
