Answer:
Option D
Step-by-step explanation:
The compounded interes formula states that:
V(t) = P (1 + r/n)^ (nt)
t = years since initial deposit  = 3
n = number of times compounded per year  1
r = annual interest rate (as a decimal)  = 4% / 100 = 0.04
P = initial (principal) investment = $500
Then V(t) = $500 ( 1 + 0.04/1)^3 = 562,43
So the correct answer is option D. 
  
        
                    
             
        
        
        
The equation<span> of a </span>line<span> is typically written as </span>y<span>=mx+b where m is the </span>slope<span> and b is the </span>y<span>-intercept. If you a </span>point<span> that a </span>line passes through<span>, and its </span>slope<span>, this page will show you how to find the </span>equation<span> of </span>the line<span>. Fill the </span>point<span> that </span>the line passes through... ( , ) Example: (3,2<span>) ...and the </span>slope<span> of </span>the line. m= Example: m=<span>3, or ... hope this helpps!!!!</span>
