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?

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.
