Answer:
76
Step-by-step explanation:
so first the equation for the situation has been given which is 
194=1/2x + 2x - 16
now you can just solve since it's a linear equation
194=2.5x -16
take 16 to the other side to get
210=2.5x
solve to get x (adult price)
which is 84
remember the. child's price is 8 less
84-8=76
 
        
             
        
        
        
The last one is the only one that will work.
For the first one the y intercept is when x = 0. The point would be 0,4
The second one gives a point of (4,0)
The third one is nonsense. (4,4) is not on this line.

Answer:
y = x - 8
Step-by-step explanation:
In order to solve this, we need to use point-slope form.:
y - y1 = m(x - x1)
Substitute the numbers into the equation:
y - (-8) = 1(x - 0)
y + 8 = x
y = x - 8
