Answer:
One adult ticket is $4 and one child ticket is $7
Step-by-step explanation:
Make a system of equations
2x + 10y = 78
8x + 5y = 67
Solve by elimination, multiply the 2nd equation by -2
2x +10y = 78
-16x -10y = -134
Add the equations
-14x = -56
x = 4
The price of one adult ticket is $4
Plug 4 in as x to find y
2(4) + 10y = 78
8 + 10y = 78
10y = 70
y = 7
The price of one child ticket is $7

Let me lay down the Given, and than I'll solve the question...
<em>Felisha</em> is 6 years older than <em>Gabriella</em><em> - (y)</em>
<em>Their Mother</em> is 2 times older than <em>Felisha</em>
<em>Their Aunt (Tanya - [x] )</em> is X years older than <em>Their Mother</em>
<em /><u><em>We are solving for how old is Tanya? ...</em></u>
**I stated Gabriella with a y instead of an X so that the equation does not look confusing, feel free to replace my y with "<em /><em>Gabriella(X)</em>", when writing/typing your answer...
**When I use the variable <em>Z</em>, this is how many years Tanya is older than the Mother...
To find how many years Tanya is older than the Mother: Z = 2 * (6 + y)
Now... the answer is: X = (2 * (6 + y)) + Z
I stated it this way, because we have to add Felisha's and Gabriella's age first, and than your multiply that age <em>Total</em> by 2 to get the Mother's age...
The answer is 1,032. (also known as answer choice A)
