well, 84 divided by 3 is 28 and if you check that by multiplying 28 with 3 you get 84 so its 28
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
The formula for compound annual interest is  A = P(1 + r)t  where  
 
A = Accumulated or final amount  (double $500 = $1000)  
P = Principal or original amount  ($500)  
r = Rate as a decimal (0.08)
t = Time in years  
 
1000 = 500(1 + 0.08)t 
2 = 1.08t  
 
Take the logarithm of both sides.  I prefer the natural logarithm ln, but if you're more comfortable with base 10 logs they will work just as well  
 
ln(2) = ln(1.08t)  
ln(2) = t*ln(1.08)
t = ln(2)/ln(1.08)
t = 9.0065 years  
 
Check:  500*1.089.0065 = $1000
