Answer:
This is pretty simple, it tells you that two tickets are worth $18, to figure out how much one would cost you just divide 18/2 and that would equal $9. So Your answer would be Each ticket sold yields $9 of profit.
Here, Let, Number of Ticket = x
Sold profit = y
Then, relation would be: 18/2 = 9
y = 9x
In short, Your Answer would be Option B) "Each ticket sold yields $9 of profit"
Hope this helps!
 
        
                    
             
        
        
        
Answer:
 
  
 

Step-by-step explanation:
Considering that The Student Council expects to 150 students for a dance, and spends $10 per student.
If the expectancy is that the number of students increases by  8%
Then since the growth is 8%
we can write the the Predicted Number of Students as a Geometric Sequence,
A.

Therefore, 

B) If we spend $10 per student on the 1st year, but the Council wants to reduce the expenditure 4% yearly. Since we want to reduce 4% we must multiply by 96%.

Therefore we can write:

C) 
The total expenditure for food must be reduced, by 4%. As long as the public goes increasing by 8% yearly this
So, 

 
        
             
        
        
        
' x ÷ 3 ' is just another way to write  ' 1/3 x ' ,
so your equation is        y = 1/3 x .
The graph of that equation is a straight line,
going through the origin, with a slope of 1/3 .
