equation csn be represented as
money left = 500 - (n-1)×4.65
so we can see in first week money left
= 500 - (1-1)×4.65= 500-0=500
which is true because first week chaya got gift card and does not spend any money. 
now lets assume that on week n money left is 327.95
so by equation 
500 -(n-1)×4.65 = 327.95
500- 327.95 =( n-1)× 4.65
n -1 = 172.05/4.65=37
n = 37+1 = 38 
in 38th week money left would be 327.95
 
        
             
        
        
        
Answer:
true
Step-by-step explanation:
hopefully this helps :)
 
        
                    
             
        
        
        

  then you figure out what you divide 56 by to get 4. which is 14. then you divide 42 by the same number 14.
 
        
                    
             
        
        
        
For the first question the answer is 
X=-9 or X=10
First you factor the left side of the question
(X+9)(X-10)=0 then u set factors equal to zero
X+9=0 or x -10=0
X=-9 or X=10
Now for question two is the second bubble of answer
        
             
        
        
        
He will be charged for 551 miles.
30283-29582=701 miles traveled in the rental vehicle.
150 of those miles are free; 701-150 = 551 miles he will be charged for.
