Answer:  $24
Step-by-step explanation:
Mariano saved $24because 
120 x 0.2=24
She payed $96
 
        
                    
             
        
        
        
So you you are trying to find the area of sphere so you would use this formula 
A=4•3.14•r^2 
And you already know that the radius is 6 so you would go ahead and plug in the numbers 
A=4•3.14•4^2
4^2 is 16 so your final equation would be
A=4•3.14•16
And your answer is 
=452.39
