Hi,

total amount he has invested is $4,950 

He has two times as much money invested at 10% than he does at 15% amount of 

15% 

10% 

5%  (4950 - x - 2x)  0r (4950-3x)

Question States: interest for the year comes to $520

 

 

         .20x = 520 - 247.50 = $272.50

             .2x = $272.50

               x = $1362.50

15%   = 1362.50 + 204.375

10%  = 2725 + 272.50

5%   = 862.50 + 43.125

CHECKING our answer***

  = 204.375 + 272.50 + 43.125 = $520

Wish You the Best in your Studies.
