Are you sure this is from GMATPrep? The wording seems funny and I don't think GMATPrep would use names like "Xiang"...

Nevertheless,

Highest selling price of the two months is 6100+16500 = 22600
Lowest selling price of the two months is 4500

Range is 22600-4500 = 18100

Answer D.

If the range of prices is 16500, and the lowest price is 6100, the highest price must be 6100+16500.

I've seen Rasheed and Malik, so why not Xiang? John and Mary are such nondescript names, anyway!
