It will take 14.7 years for Armando's money to double.
Option C
<u>Explanation:</u>
The rule of 72 is generally used to estimate the number of years required to double the invested money at a given annual rate of return. And alternatively to find the number of years required to double the money at a given interest rate, we have to just divide the interest rate into 72.
Here, the interest rate is 4.9%. Therefore, it would be as follows

Rule 72 can be used to identify the following:
- Number of years it takes an investment to double, 
- Number of years it takes debt to double, 
- The interest rate must earn to double in a time frame, 
- Number of times debt or money will double in a period of time.
 
        
                    
             
        
        
        
It’s 3 because (x,y) & your coordinates were (3,5) so x is 3. x stays the same, hope this helps
        
             
        
        
        
This is the concept of statistics. The correct answer is:
There are twice as many participants in the 0-19 age group than in the 60-79 age group. This is because:
Number of participants in the age group 0-19 is 40 participants
Number of participants in the age group 60-79 is 20 participants.
From the above we see that the age group 0-19 is double the number of age group 60-79 years old. 
Therefore our answer is option C
