Answer: Let's call the price of an adult's ticket "A" and the price of a child's ticket "C". We can use this information to set up a system of equations to solve for A and C:

From the first piece of information, we know that:

3A + 4C = 132

From the second piece of information, we know that:

2A + 3C = 94

Now we can solve for A and C using any method of solving a system of equations. One possible method is to use elimination:

Multiply the second equation by 2:

4A + 6C = 188

Subtract the first equation from the second equation:

4A + 6C - 3A - 4C = 188 - 132

Simplify and solve for A:

A + 2C = 56

A = 56 - 2C

Substitute this expression for A into either of the original equations:

3(56 - 2C) + 4C = 132

Simplify and solve for C:

C = 10

Substitute this value for C into the expression we found for A:

A = 56 - 2(10) = 36

Therefore, the price of an adult's ticket is $36, and the price of a child's ticket is $10.
