In May 15 cars
L = 4500
R = H - L = 15,000
H = 195000

In June 10 cars
L =6100
R = H - L = 16500
H = 22600

The prices range ( 4500 , 6100 , 19500 , 22600 )
Range of the 25 used cars in May + Jun = 22600 - 4500 = 18100

Range = Lowest - Highest
In May Lowest = 4500
Range = 15000 => Highest = 19500

In July
Lowest = 6100
Highest = 16500+6100 = 22600

For the two months Range = Highest in two months - Lowest in two months = 22600-4500 = 18100
