Let's assume there are 52 weeks in a year,
so we have , rate= 6.4/52= 0.123% 
now ,
c.i = 5000[(1+0.123/100)^3×52 -1]
= $1056.911

Use photo math for this :)
        
                    
             
        
        
        
x < -  
add 
 to both sides
- 3x > 
 + 
- 3x > 
 ( divide both sides by - 3 )
note that when we divide/ multiply by a negative quantity we must reverse the inequality symbol
x < -
