Pearson doesn't provide explanations, so I have no clue how to set this up.
Any help would be appreciated.

range in May = 15000
Lowest in May = 4500
therefore highest in may = 19500
Range in June = 16500
Lowest in June = 6100
Higest in june = 22600
Therefore range for all cars sold = 22600-4500 = 18,100
Lowest in May = 4500
therefore highest in may = 19500
Range in June = 16500
Lowest in June = 6100
Higest in june = 22600
Therefore range for all cars sold = 22600-4500 = 18,100

Answer? $18,100
May figure,
Range = $15,000
Lowest Selling price = $4,500
So highest selling price = $(4500 + 15000) = $19,500
June figure,
Range = $16,500
Lowest Selling price = $6,100
So highest selling price = $(6100 + 16500) = $22,600
Range of the SP in both May and June = Highest SP - Lowest SP
= $22,600 - $4,500 = $ 18,100
