ANSWER
![\$12](https://tex.z-dn.net/?f=%5C%2412)
EXPLANATION
Let the price of one senior ticket be s.
Let the price of one child ticket be c.
Three senior tickets and one child ticket sold for $40. This implies that:
![3s+c=40](https://tex.z-dn.net/?f=3s%2Bc%3D40)
Three senior tickets and two child tickets sold for $52. This implies that:
![3s+2c=52](https://tex.z-dn.net/?f=3s%2B2c%3D52)
From the first equation, make 3s the subject of the formula:
![3s=40-c](https://tex.z-dn.net/?f=3s%3D40-c)
Substitute this into the second equation:
![40-c+2c=52](https://tex.z-dn.net/?f=40-c%2B2c%3D52)
Solve the equation for c by collecting like terms:
![\begin{gathered} 2c-c=52-40 \\ \Rightarrow c=\$12 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%202c-c%3D52-40%20%5C%5C%20%5CRightarrow%20c%3D%5C%2412%20%5Cend%7Bgathered%7D)
Therefore, a child ticket goes for $12.

Answer:
radius = 40 / 2 = 20ft
Circle area = πr² = π × 20² = 1256.6 sq. ft
B(x) = | x + 4 |
b(-10) = | -10 + 4 |
b(-10) = | -6 |
b(-10) = 6 <====
