The diagram above shows the breakdown by age of the 1,560 people who attended the Spring Island
Concert last weekend. How many people between the ages of 18 and 34 attended the concert?
Correct Answer:
1,014
Explanation/Reference:
Of the concert attendees, 41% were between the ages of 18-24 and 24% were between the ages of 25-
3 4. Therefore, 41 + 24 = 65% of the attendees, or (1,560)(0.65) = 1,014 people between the ages of 18
and 34 attended the concert.

If -6b + 2a - 25 = 5 and a/b + 6 = 4, what is the value of (b/a)2?
Correct Answer:
1/4
Explanation/Reference:
Solve-6b + 2a - 25 = 25for a in terms ofb: -6b + 2a - 25 = 5, -3b + a = 15, a = 15+3b. Substitute a in terms
of b into the second equation: Substitute b into
the first equation to find the value ofa: -6b + 2a - 25 = 5, -6(-3) 2a - 25 = 5, 18+2a = 30, 2a = 12, a = 6.
