Let an adult ticket cost a.
Let a child ticket cost c.

"One person buys 8 children's tickets and 1 adult ticket and pays $16.50."

8c + a = 16.5

"Another person buys 6 children's tickets and 1 adult ticket and pays $14.00."

6c + a = 14

We have a system of equations.

8c + a = 16.5
6c + a = 14

Subtract the second equation from the first equation.

2c = 2.5

c = 1.25

Now substitute 1.25 for c in the first equation and solve for a.

8(1.25) + a = 16.5

10 + a = 16.5

a = 6.5

Answer: An adult ticket costs $6.50, and a child ticket costs $1.25.
