Answer 
Find out the what was the price of the stereo .
To prove 
Let us assume that the price of the stereo be x .
As given 
Consumer Math The sales tax in the town where Amanda lives is 7%. 
7% is written in the decimal form 

= 0.07
As given
Amanda paid $35 in sales tax on a new stereo .
Than the equation becomes
x × 0.07 = 35 

solving the above
x = $ 500 
Therefore the price of the stereo is $ 500 .
Hence proved
 
        
             
        
        
        
The expression for the greatest common factor of 20 and 30 using the distributive property is 10(2 + 3)
Pounds of ice = 20
Number of cups = 30
The relation for the distributive property : 
a × (b + c) 
Expand ;
a × (b + c) = (a × b) + (a × c) = ab + ac
Finding the greatest common factor of 20 and 30 ;
(2 × 10) + (3 × 10)
According to the distributive property 
(2 × 10) + (3 × 10) = 10(2 + 3)
Therefore, the expression for the greatest common factor is 10(2 + 3)
