Initial Deposit = $7000
It means P= $7000
rate of interest = 10%
So , r = 0.10
compounded quarterly , so  n = 4
and we have to find the amount after 5 years , So t = 5
Now the formula we use here is 





So amount after 5 years = $11470.315
 
        
                    
             
        
        
        
50 - 5n = 15
if you need to find the number n then
50 - 5n = 15
-5n = -35
  n = 7
