a)15,600
b)15,750
c)16,820
d)18,100
e)19,200

This seems to be a very simple problem but i can't get my head around it. I guessed the answer correct but would like to know how to solve it.

May
Range = 15000
Lowest Selling price = 4500
Highest selling price = 15000+4500 = 19500

June
Range = 16000
Lowest Selling price = 6100
Highest selling price = 16000+6100 = 22100


Combined May & June
Highest selling price = 22100
Lowest selling price = 4500

Range = 22100-4500 = 17600

Are all the values and the answer choices correctly posted? I dont see this in any of the answer choices.
