You can put this solution on YOUR website!
Let +x+ = the number of pounds that you buy
Let C = the total cost of watermelon bought
+C+=+.49%2A25+%2B+%28+x+-+25+%29%2A%28+.49+-+.15%2A.49+%29+
+C+=+.49%2A25+%2B+%28+x+-+25+%29%2A%28+.85%2A.49+%29+
+C+=+12.25+%2B+.4165%2A%28+x+-+25+%29+
+C+=+.4165x+%2B+12.25+-+10.4125+
+C+=+.4165x+%2B+1.8375+
---------------------
check answer
If you buy 25 pounds:
+C+=+.4165%2A25+%2B+1.8375+
+C+=+10.4125+%2B+1.8375+
+C+=+12.25+
which is the same as no discount
+C+=+.49%2A25+
+C+=+12.25+
OK
