You can put this solution on YOUR website!
She sold +4+ kg for as much as she paid for +5+ kg
+4%2F5+=+1%2F%28+5%2F4+%29+
She sold +1+ kg for as much as she paid for +5%2F4+ kg
-----------------------
She actually sold +50+-+5+=+45+ kg
She sold +1%2A45+ kg for as much as she paid for +%285%2F4%29%2A45+ kg
She sold +45+ kg for as much as she paid for +56.25+ kg
-------------------------------
I'll say the price/kg that she bought them at was +100+ monetary units/kg
+50%2A100+=+5000+ monetary units was the buying price for +50+ kg
--------------------------------
+56.25%2A100+=+5625+ monetary units was the selling price for +45+ kg
--------------------------------
Her profit was +5625+-+5000+=+625+ monetary units
The % profit was:
+%28+625%2F5000+%29%2A100+=+12.5+
12.5% profit

Just my way of doing it. You might
like a different way better.
Hope I got it!
