You can put this solution on YOUR website!
Let +x+ = amount invested in bonds
+70000+-+x+ = amount invested in CD
given:
+.13x+%2B+.03%2A%28+70000+-+x+%29+=+5000+
+.13x+%2B+2100+-+.03x+=+5000+
+.1x+=+5000+-+2100+
+.1x+=+2900+
+x+=+29000+
+70000+-+x+=+41000+
$29,000 should be invested in bonds
$41,000 should be invested in CD
