Answer:
The price of an adult's ticket is $18.5 and the price of a child's ticket is $6.5
Step-by-step explanation:
Let
x ------> the price of an adult's ticket
y -----> the price of a child's ticket
we know that
8x+5y=180.50 ------> equation A
12x+6y=261.00 ------> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both graphs
The solution is the point (18.5,6.5)
see the attached figure
therefore
The price of an adult's ticket is $18.5 and the price of a child's ticket is $6.5
