Final answer:

The price of a senior citizen ticket is $8, and the price of a child ticket is $13. Let's denote the price of a senior citizen ticket as x and the price of a child ticket as y. The price of a senior citizen ticket and the price of a child ticket. We can use a system of equations.

Step-by-step explanation:

To find the price of a senior citizen ticket and the price of a child ticket, we can use a system of equations. Let's denote the price of a senior citizen ticket as x and the price of a child ticket as y. Using the given information, we can set up the following equations:

4x + 14y = 214 (equation 1)

7x + 7y = 147 (equation 2)

We can solve this system of equations by either substitution or elimination. Let's use elimination to eliminate the variable x. Multiply equation 1 by 7 and equation 2 by 4: 28x + 98y = 1498 (equation 3)

28x + 28y = 588 (equation 4)

Subtract equation 4 from equation 3: 28x - 28x + 98y - 28y = 1498 - 588 and 70y = 910

Divide both sides by 70: y = 13

Substitute the value of y back into equation 2:

7x + 7(13) = 147

7x + 91 = 147

Subtract 91 from both sides: 7x = 56

Divide both sides by 7: x = 8

Therefore, the price of a senior citizen ticket is $8, and the price of a child ticket is $13.
