Remember that range is the highest minus the lowest.

The long way (took me 30 secs to calculate)
May:
x-4500=15000
x=19500

June:
x-6100=16500
x=22600

The highest value is 22600, the lowest is 4500
22600-4500=18100

From scanning the problem you can see that the highest range value for the two months is 16500. Solve for the highest selling price (22600) and locate the lowest selling price which is 4500.

apprx 20 seconds.
