Answer:
C.
Step-by-step explanation:
= ![\sqrt[3]{8}^{x}\\](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D%5E%7Bx%7D%5C%5C)
= Since ![\sqrt[3]{} = ^{1/3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%7D%20%3D%20%5E%7B1%2F3%7D)
= So, It becomes :
= 
Price of an adult ticket: $25
Price of a child's ticket is 25-0.20(25) = $20
Total cost = 2 adult tickets + 4 child tickets
= 2(25)+4(20)
= 50+80 = $130
A will be 7 x 5
B will be 10x10
8 + 4 = 12 is the equation.
