<h3>
Answer: C) 4</h3>
=====================================================
Work Shown:
Applying the tangent-secant theorem will allow us to solve for x
x*(x+5) = (x+2)^2
x^2+5x = (x+2)*(x+2)
x^2+5x = x^2+4x+4
5x = 4x + 4 ..... subtracting x^2 from both sides; terms cancel
5x-4x = 4
x = 4
------------------
Check:
Plug in x = 4
x*(x+5) = (x+2)^2
4*(4+5) = (4+2)^2
4*(9) = (6)^2
36 = 36
The answer is confirmed.

Let us say,
Price of adult ticket=x
Price of child ticket =y
On the first day ticket sales the school sold 4 adult tickets and 12 child tickets for total of $80
4x+12y=80.............(1)
took $41 on the second day by selling 1 adult ticket and 10 child tickets
1x+10y=41.............(2)
x=41-10y..............(3)
plugging the value of x from equation (3) in equation (1) we get,
4(41-10y)+12y=80
164-40y+12y=80
84=28y
y=3
plugging this value of y in equation (2) we get,
1x+10(3)=41
x=11
Price of adult ticket= 11 dollars
Price of child ticket = 3 dollars
