I'm sorry you need to be more clear I don't understand the question.
Your equation should be
$4(40 tickets) + $5(X) = $400
160 +5x = 400
-160 -160
0 5x = 340
divide both sides by 5
5x/5 = 340/5
x = 68
so they need to sell 68 tickets at the door.
4(40) + 5(68) = 400
160 + 340 + 400
400 + 400
Answer:
96

Yes, it this somehow related to mathematics? Was this a question?
Answer:
D. 
Step-by-step explanation:
We can use a process of elimination in order to easily solve this.
The shape of 
will be two diagonal lines that meet at (0,0)
Will be an upside down parabola
Will be a line with a slope of -1.
This means that the answer must be D
