Answer by checkley77(12844)   (Show Source):
You can put this solution on YOUR website! .09x+.04(29,000-x)=1,760
.09x+1,160-.04x=1,760
.05x=1,760-1,160
.05x=600
x=600/.05
x=12,000 amount invested @ 9%.
29,000-12,000=17,000 amount invested @ 4%.
Proof:
.09*12,000+.04*17,000=1,760
1,080+680=1,760
1,760=1,760
