You can put this solution on YOUR website!
let,
k -> kelly
r -> renee
n -> nina
given,
k + r + n=20000
k = r - 4000
+n+=+2r%2F3+
thus,
+%28r-4000%29+%2B+r+%2B+%282r%2F3%29+=+20000+
+2r+%2B+2r%2F3+=+20000+%2B+4000+
+%286r+%2B+2r%29%2F3+=+24000+
+8r+=+24000+%2A+3
+r+=+%2824000+%2A+3%29%2F8+
+r+=+9000+
and kelly is 9000-4000=5000
nina is +%282+%2A+9000%29%2F3+ = 6000
