Question 306895
103 melons were initially bought.
If you divide 1.50 into 200.00, you get 133.33(approximatly) OR 200=1.5x "x" being melons. So wath this says is that if you sell 133melons then you'll get all profit back. But if there were 30melons still left, then you subtract30 from 133.33(133.33-30), equals 103.33 approximatly 103. 
If I'm wrong, forgive!
