You can put this solution on YOUR website!
Let m = Melissa's earnings/hr
Let j = Jonathan's earnings/hr
Let l = Louise's earnings/hr
(1) +m+=+j+%2B+.1j+
(2) +l+=+j+-+.25j+
-----------
(2) +j%2A%281+-+.25%29+=+l+
+j+=+l%2F.75+
(1) +m+=+j%2A%28+1+%2B+.1%29+
(1) +m+=+%28l%2F.75%29%2A1.1+
(1) +l%2Fm+=+.75%2F1.1+
(1) +l%2Fm+=+75%2F110+
+l%2Fm+=+15%2F22+
