To triple, means to multiply that number by 3.
To cube means to times that number by it's self three times.
So, in conclusion, the answer would be Kayla. 
        
                    
             
        
        
        
Let the price of a ticket be originally T dollars, and the number of clients be N.
let the price decrease by x  3-dollars.
"there is an average increase of 4 people for every $3 decrease on the price of the ticket."
means: 
if the price is decreased by 1-3$:
 then N become N+4, and T becomes T-3    
if the price is decreased by 2-3$:
 then N become N+4+4=N+2*4, and T becomes T-3-3=T-2*3    
 So if the price is decrease by x-3 dollars:
N  becomes N+4x, and T becomes T-3x
"A circus owner sells an average of 340 tickets when the price of a ticket is $75."
In this case N=340, and T=75$
If the owner does not change the price ticket, x=0, the revenue is 340*75,
If the owner decreases the price of the tickets by x-3$, then the revenue will be 
(N+4x)(T-3x)=(340+4x)(75-3x) dollars,
If R is the function of the revenue depending on x, then 
R(x)=(340+4x)(75-3x) dollars
 
Answer: R(x)=(340+4x)(75-3x) dollars

Answer:
8a+1=33
Step-by-step explanation:
you can solve 3a-2=10 by simplifying to 3a=12, so a=4. Then you replace the a in 8a+1 with 4 to get 32+1, which is 33
