Explanation:</h2><h2>
</h2>
In this problem, we know that Harry saved $100 each week for 8 weeks. In other words, he saved a total amount of money:

We know that he earned $48 on his savings of $800, so for every $100 the interest (I) he earns is:

So, in conclusion Harry did earn $6 in interest for every $100
 
        
        
        
H is the answer 
 and the line of the symmetry is like the picture
 
        
        
        
The correct answer is:  [D]:  "distributive" .
