Question 986140: Deandre invested his savings in two investment funds. The $6000 that he invested in fund A returned a 2% profit. The amount that he invested in fund B returned a 5% profit. How much did he invest in fund B, if both funds together returned a 4% profit?

You can put this solution on YOUR website!
Let A be the amount invested in Fund A. THen 6000-A is the amount invested in Fund B
You are told Deandre got a 4% return on 6000.

6000+%2A+0.04+=+%28A%2A0.02%29++%2B+%286000-A%29%2A+0.05
240+=+0.02A+%2B+300+-+0.05A
-60+=+-0.03A
%28-60%29%2F%28-0.03%29+=+A
2000+=+A
So he invested 6000-2000 = 4000 in fund B
