Anita's sister had $6000 to invest. She invested part of this sum at 4% and the other part at 6%. If the annual return on the 6% investment is $15 more than the annual return on the 4% investment, find how much is invested at 6% rate.

Let the amount invested @ 6% =A

Amount invested @ 4% =6000 - A

Let the return on 4% investment =R

0.04*[6000 - A] = R.................................(1)

0.06A =R + 15...........................................(2), solve for A, R

**A = $2,550 - amount invested @ 6% $6,000 - $2,550 =$3,450 - amount invested @ 4%**

**R = $138.00 - return on the 4% investment. $138 + $15 =$153 - return on the 6% investment.**
