You can put this solution on YOUR website! Sung invested his savings in two investment funds. The amount he invested in Fund A was 4 times as much as the amount he invested in Fund B.

Let amt. invested in B = "x".
The amt. invested in A = "4x"
--------------------------------------------
Equation:
interest + interest = interest
0.02(4x) + 0.04(x) = 1440
Multiply thru by 100 to get:
2(4x) + 4(x) = 144000
12x = 144000
x = $12,000 (amt invested in B)
4x = $48,000 (amt. invested in A)
=================================
