Question 888423: A community theater had a revenue of $30, 495 from the sale of adult tickets and children tickets. adult tickets cost $9 each and children's tickets cost $6.50 each, and there were 3800 tickets sold. What represents the number of children's tickets sold according to Cramer's Rule?
Answer by JulietG(1812)   (Show Source):
You can put this solution on YOUR website! If all 3800 tickets were adult tickets, the revenue would have been 3800*9 = 34,200.
The actual revenue was 30,495, a difference of 3,705.
The difference in adult and child tickets is 9=6.50, or 2.50
3705 / 2.50 = 1482 child's tickets
 children's tickets at $6.50 = $9633
3800-1482 = 2318 adult tickets at $9 = $20,862
9,633 + 20,862 = $30,495
.
I'm not familiar with Cramer's rule, but the above is the answer.
