Answer:
Step-by-step explanation:
Let the students price = x
Let the teacher's price = y
34x + 3y = 635
34y = 299.54
y = 299.54 / 34
y = 8.81
The only way to do this is to assume that students and teachers are charged the same amount for admission. But the question should say so. 
So x = y
37x = 635.66
x = 635.66 / 37
x = 17.18
So the total spent per student was
8.81 + 17.18 = 25.99
 
        
             
        
        
        
Answer:
D
Step-by-step explanation:
I'm not really 100% sure this is a weird question but I would assume D because if something is not proportional or doesn't conform to an equation, it has no slope
 
        
             
        
        
        
Answer:
0.33
Step-by-step explanation:
If you have the number 1 and divide it by 100, you get 1/100, 0.01, or 1% of 1. If you multiply 1/100 by 33, you get 33/100, 0.33, or 33% of 1.
