Answer:
Option D. 3:1, $120
Step-by-step explanation:        
The complete question in the attached figure     
Part 1) What is the ratio between the amount of money contributed by Anna and the amount contributed by her mother?       
Let    
x -----> the amount of money contributed by Anna      
y ----> the amount of money contributed by her mother     
we know that    
Looking at the table   
The value of x is equal to    
   
The value of y is equal to    
    
Find the ratio  x/y   
substitute the values  
 
   
Part 2)  What was the total amount saved in April?     
we know that         
To find out the  total amount saved in April, adds Mon's contribution in April plus Anna's contribution in April            
so

Answer:
degree of polynomial = 5
leading term = 
leading coefficient = 2
constant term = -6
Step-by-step explanation:

(i) The degree of the polynomial = 5. That is, the highest power of x
(ii) Leading term =  . This is the term with the highest power of x.
. This is the term with the highest power of x.
(iii) Leading Coefficient = 2. That is, the coefficient of the leading term ( )
)
(iv) Constant term = -6. This is the term that is independent of x or the term in which x doesn't appear.
